The entire lineup is integrated with high-strength flanged connections compliant with industrial standards, ensuring robust structural integrity and leakage-free sealing under conditions of high flow rates and massive jet blowing volumes. Utilizing an advanced DC pulse (Direct Current Pulse) actuation mechanism, the valve radically revolutionizes traditional operations by eliminating the need for continuous power supply to maintain an open state. It only requires a microsecond-level electrical pulse signal from the controller during the instantaneous opening and closing transitions; for the remainder of the time, the valve maintains its state via an internal mechanical and aerodynamic self-locking design. This results in exceptional low power consumption, zero heat generation, and an elongated operational lifespan. Optimally calibrated for low-to-medium pressure systems, the YSG series exhibits millisecond-level responsive triggering and powerful tight shut-off under low operational pressures and differentials ranging from 0.3 to 8 bar. Available in Premium Stainless Steel SS304 (JF Series) and High-Grade Cast Iron (CF Series), the valve bodies accommodate water, industrial liquids, compressed air, and non-aggressive gases. This makes them an ideal core control component for modern environmental filtration, chemical processing, water treatment, and metallurgical industries. Product Image:YSG Large-Calibre Pulse Solenoid Valve Feature Expanded Bore & Fluid Dynamics Optimization: Optimized internally for DN65 to DN200 pipelines. The spacious and rounded geometry of the internal flow chamber completely minimizes dead corners and turbulence, lowering the flow resistance coefficient and yielding a flow capacity (Kv value) that far surpasses standard solenoid valves. Low Power Consumption & Zero Heat Dispersal: Traditional solenoid valves experience extreme coil heating during prolonged energized opening, often leading to coil burnout.

The YSG series DC pulse type solenoid valve (nominal diameter ranging from DN15 to DN80) is a high-longevity, ultra-fast response control device specially designed and developed for automated fluid control of environmental baghouse dust collector pulse jet cleaning, agricultural spray irrigation, industrial high-frequency humidification, and instantaneous large-flow multi-phase fluid pipelines. As a core execution element in various fluid control networks and pulse jet cleaning control loops, this series features comprehensive flow channel optimization design targeting the conventional working pressure range from 0.3bar to 8bar (0.03-0.8MPa). It focuses on solving technical industry difficulties common in traditional solenoid valves, such as severe heat generation and high power consumption under long-term energized states, and vulnerability to body cracking or severe actuation response lag when enduring high-frequency instantaneous switching impacts. The valve body of this series innovatively utilizes industrial-grade high-strength reinforced nylon PA66 material (where the "SL" suffix represents specialized lightweight high-longevity versions), possessing outstanding characteristics against water hammer, mechanical vibration, and physical wear. Connection types cover G/NPT threads, high-standard flanges, and convenient unions, completely and seamlessly adapting to the diverse assembly sites of modern industrial and environmental systems. This series of valves utilizes a DC pulse (also known as bistable latching type) actuation mechanism. Its core advantages lie in astonishingly ultra-low power consumption and high-frequency millisecond-level switching. Distinct from ordinary solenoid valves that require continuous electricity to maintain an open state, the DC pulse valve integrates high-performance magnetic latching components internally. When the control system (such as a pulse controller or PLC) transmits a millisecond-level forward DC electrical pulse signal (such as DC24V, lasting several milliseconds to dozens of milliseconds) to the solenoid valve coil, the moving iron core is rapidly attracted upward by magnetic force, opening the balanced pilot hole, and the main diaphragm (or main valve core) is instantly pushed open by high-pressure fluid, thoroughly opening the valve. Subsequently, even if the coil is completely de-energized, internal permanent magnetic materials can rigidly hold the iron core in the open position. Only when the system transmits a reverse DC electrical pulse signal to the coil again will the permanent magnetic field be neutralized, and the moving iron core rapidly resets and locks under the rigid drive of an ultra-strong main spring force, completely closing the main valve port. This bistable control structure perfectly avoids insulation aging risks caused by long-term coil heating, rendering actuation responses exceptionally crisp and clean.Product Image:YSG Electromagnetic Pulse Valve Feature Heavy-duty specialized electrical flameproof safety enclosure, certified by national authority explosion-proof testing: Core electrical parts of the ZCSB series are completely sealed inside a high-strength precision-cast metal flameproof chamber. Enclosure joint faces strictly execute precise flameproof gap and length control standards. Once an internal short circuit, overload, or electrical spark from switching induces an internal deflagration, the flameproof chamber can rigidly withstand the internal explosion pressure, and the jetted flame and high-heat gas are deeply cooled and extinguished through the precise flameproof gaps, absolutely unable to ignite inflammable and explosive gases, dust, or gas environments outside the valve body. 0 to 16bar ultra-wide full pressure bearing control range, realizing all-around stable switching of direct acting and semi-direct acting mechanisms: Distinct from ordinary solenoid valves with narrow working pressure ranges, this series can realize highly rigid and precise opening and closing from 0bar (zero pressure differential, gravity gravity-flow, no initial pressure) up to a 16bar high-pressure fluctuating state. Whether for low-pressure gas transmission, medium-pressure liquid circulation, or conventional 1.6MPa pipeline safety shut-off, actuation responses are consistently stabilized at millisecond levels. Excellent multi-medium compatibility design, fully conquering high-pressure gases, liquids, steam, and oils below 20CST: Targeting characteristics on industrial sites where multiple media such as water, combustible gases, saturated steam, and low-viscosity light oils alternate circulation, the internal flow channel of the ZCSB series undergoes deep optimization against fluid shearing and grease accumulation. Sealing pairs can be customized with high-performance PTFE, Viton, or specialized wear-resistant composite elastomers according to specific media, perfectly overcoming steam temperature differences and oil viscosity resistance (less than or equal to 20CST) to ensure long-lasting zero internal leakage. Large-bore up to DN200 heavy-walled robust valve body, seamlessly resisting external mechanical stress of harsh field pipelines: Product specifications feature a massive span (DN10 to 200). Stainless steel and cast iron flange versions have their load-bearing wall thicknesses designed strictly in accordance with high-pressure industrial pipeline standards, possessing an immense safety factor. Precise G/NPT thread interfaces engage tightly, and high-specification flange faces can perfectly absorb pipeline tensile or torsional stresses generated by thermal expansion and contraction due to site temperature differences, significantly enhancing continuous service life of equipment on inflammable and explosive production lines.

The ZCSB series flameproof 2-way 2-position explosion-proof solenoid valve (nominal diameter ranging from DN10 to DN200) is a high-safety rating execution device specially designed and developed for inflammable, explosive hazardous environments, high-reliability industrial pipe networks, and heavy-duty multi-medium fluid automated control. As a core execution element in petrochemical industries, natural gas transmission and distribution, coal mine gas drainage, gas station liquid level control, and specialized inflammable gas pipelines, this series features comprehensive structural reinforcement targeting high pressure bearing conditions up to 16bar (1.6MPa) and complex on-site electrical explosion-proof environments. It focuses on solving fatal potential hazards where traditional solenoid valves generate electrical sparks during coil switching or short circuits that induce instantaneous explosions of external environments. It also addresses industry difficulties under large-bore high-pressure environments, such as sealing failures and actuation stagnation when conveying viscous oil products, high-temperature steam, or corrosive liquids. The series provides two driving mechanisms: direct acting (small bore) and semi-direct acting (large bore) based on the bore span, and the entire series is equipped with a specialized heavy-duty flameproof enclosure certified by national explosion-proof authorities. Valve body materials cover premium brass, high-purity SS304 stainless steel, and heavy-duty cast iron (where versions with the "F" suffix represent large-specification flange versions). Interfaces perfectly support G/NPT threads and international standard flanges, fully satisfying production safety needs in specialized hazardous industrial fields. This series of valves belongs to normally closed 2-way 2-position automatic valves. Its core essence lies in the seamless combination of electrical flameproof enclosure rigid safety blocking technology and robust 16bar bidirectional sealing shut-off characteristics. When the electromagnetic coil is de-energized, an ultra-high rigidity main return spring applies direct rigid pre-tightening force through the linkage shaft, pressing the specialized high-density wear-resistant sealing assembly tightly against the main valve seat. Because the nominal pressure of this series reaches up to 16bar, the heavy-walled valve body and powerful spring can perfectly resist violent impacts generated by high-pressure fluids during reverse or forward flow, achieving absolutely reliable and long-lasting zero-leakage physical obstruction. When the electromagnetic coil is energized, the electromagnet located inside the specialized explosion-proof chamber instantly generates a powerful magnetic field attraction force. For small-bore direct acting structures, the moving iron core directly overcomes spring resistance to lift the valve core rigidly; for large-bore semi-direct acting structures from DN50 to DN200, the back-kick mechanical linkage assembly first opens the internal balancing pilot hole to quickly relieve the high-pressure medium above the main valve core, and then rigidly lifts the main sealing assembly. Even if the system pipeline is under an extreme condition of zero pressure differential without any pressure difference, or when pressure fluctuates violently within 16bar, the valve is rigidly and linkedly controlled by the electromagnetic assembly and mechanical structure. The switching response speed reaches millisecond levels, effectively avoiding valve switching lags caused by insufficient pressure differential or oil product viscosity damping in large-specification high-pressure bearing environments of ordinary pilot valves.Product Image:ZCSB Explosion-Proof (Flameproof) 2/2-Way Solenoid Valve Feature Heavy-duty specialized electrical flameproof safety enclosure, certified by national authority explosion-proof testing: Core electrical parts of the ZCSB series are completely sealed inside a high-strength precision-cast metal flameproof chamber. Enclosure joint faces strictly execute precise flameproof gap and length control standards.

The ZK series vacuum and low-positive-pressure dual-use solenoid valve (nominal diameter ranging from DN2.5 to DN100) is a high-airtightness, bidirectional pressure-resistant fluid control device specially designed and developed for industrial vacuum systems, negative-pressure suction networks, vacuum packaging, and atmospheric/low-positive-pressure gas-liquid circulation pipelines. As a core execution element in vacuum engineering and scientific instrument control loops, this series features comprehensive structural optimization targeting extreme negative pressure vacuum conditions from -1bar to 0bar and conventional low-positive-pressure conditions from 0bar to 1bar. It focuses on solving technical industry difficulties where ordinary industrial solenoid valves are highly prone to reverse suction leakage under vacuum negative pressure, diaphragms being sucked flat in reverse, and the inability to actuate properly under completely zero pressure differential environments. The series adopts direct acting drive for small-bore valves and semi-direct acting linkage drive for large-bore valves. It offers multiple premium valve body materials including brass and SS304 stainless steel (where JF represents high-strength flange versions), and interfaces cover G/NPT thread and standard flanges, widely matching vacuum smelting, medical negative pressure suction, semiconductor vacuum equipment, food packaging machinery, and low-pressure fluid environmental treatment core industrial fields. This series of valves utilizes pure direct acting or semi-direct acting mechanisms based on the bore size, belonging to the normally closed automatic valve type. Its core advantage lies in the fact that its opening and closing are completely independent of the medium pressure differential inside the pipeline, possessing excellent bidirectional sealing performance. When the electromagnetic coil is de-energized, the high-elasticity return spring applies direct force through the main valve shaft, driving the specialized vacuum-type sealing core downward rapidly to press it firmly against the main valve seat. Whether the upstream end of the valve is in an absolute vacuum state of -1bar or the downstream end has a slight positive pressure within 1bar, the specialized dynamic sealing pair structure can rigidly counteract interference brought by the bidirectional pressure differential, achieving tight dead shut-off with an ultra-low leakage rate. When the electromagnetic coil is energized, a specially customized heavy-duty electromagnetic assembly generates a powerful electromagnetic attraction force. For small-bore direct acting valves (such as ZK-025, etc.), the electromagnetic force directly overcomes the spring force to lift the valve core, achieving microsecond-level switching. For large-bore semi-direct acting valves (such as DN15~100 specifications), the moving iron core first opens the pilot hole to balance the cavity pressure through an internally specialized back-kick linkage structure, and then rigidly lifts the entire main valve core assembly. Even in an extreme condition where the system is in an absolute pure vacuum state without any pressure differential, the valve can be thoroughly pulled open by the mechanical linkage, the main valve port opens instantly, and the medium restores large-flow unhindered passage. Once the coil is de-energized, the mechanical structure resets at high speed within milliseconds, perfectly eliminating the common industry problem where traditional valves actuate sluggishly or fail to actuate under negative pressure vacuum conditions.Product Image:ZK Vacuum Solenoid Valve Feature Bidirectional pressure-resistant sealing structure balancing vacuum and micro positive pressure, ensuring mechanical rigid switching stability across full working range: Traditional pilot solenoid valves must rely on a forward pressure differential of no less than 0.3bar to open, and reverse vacuum negative pressure will cause sealing failure or diaphragm damage. The ZK series applies anti-negative-pressure deep processing to its direct acting and semi-direct acting structures, capable of realizing mechanical forced rigid opening and closing across the ultra-wide working range of -1bar to 1bar (covering vacuum, zero pressure differential, and low micro positive pressure conditions) cleanly and neatly without any lag. Micron-level extreme ultra-low leakage rate vacuum sealing face design, maintaining high system vacuum long-term: As a specialized vacuum valve, the ZK series performs extreme precision polishing and calibration on its internal dynamic sealing pairs. Seals select high-density, anti-tearing, low outgassing rate specialized Viton or high-performance composite elastomers, greatly reducing micro molecular outgassing of materials themselves under high vacuum environments. Coordinated with refined sealing faces across the entire series, it can perfectly block reverse osmosis of trace gas molecules, ensuring long-term airtight security of high-vacuum chambers. Straight-through large channel anti-clogging design without mechanical pilot holes, demonstrating extremely high tolerance to multi-phase fluid impurities: Small-bore pure direct acting and large-bore semi-direct acting mechanisms completely abandon micron-level pilot small holes that easily clog in traditional solenoid valves. Internal channels are open and straight-through. When conveying trace water, humid gases, mixed liquids, or industrial gases with fine dust brought by vacuum suction systems, physical jamming and scaling are highly resistant to occur, and the overall reliability of product operation receives a step-like upgrade. Premium brass and SS304 stainless steel multi-material bodies, completely matching anti-corrosion and high-cleanliness requirements: Targeting the rigorous requirements of semiconductor, medical instruments, or chemical vacuum pipelines for high cleanliness, anti-oxidation, and acid-alkali resistance, the entire series offers precision forged H59 brass and high-purity SS304 stainless steel. Valve interiors undergo deburring and degreasing cleaning, and the stainless steel version can perfectly resist long-term washing by humid gases and water flow, ensuring medium purity. Both thread and flange interfaces are strictly refined according to international standard dimensions.

The ZCM series semi-direct acting automatic gas and low-pressure gas-liquid solenoid valve (nominal diameter ranging from DN10 to DN100) is a high-security, large-bore fluid control device specially designed and developed for automated pipeline control of gas safety, gas drainage, low-pressure large-flow, and atmospheric pressure vacuum pipelines. As a core execution element in inflammable and explosive gas pipe networks and various industrial low-pressure fluid control loops, this series features deep structural optimization targeting low pressure below 4bar (0.4MPa), zero-pressure conditions, and the chemical characteristics of specialized media like gas. It focuses on solving common industry pain points under ultra-low pressure environments, such as the inability of traditional pilot valves to open due to insufficient pressure differential, and the tendency of pure direct acting valves to overheat and burn out due to excessive coil power consumption under large-bore conditions. The series offers multiple premium valve body materials including brass, SS304 stainless steel, and heavy-duty cast iron (where JF/CF represents high-strength flange versions of different materials). Small-bore valves utilize G/NPT thread connections, while large-bore valves adopt international standard flange connections, perfectly matching urban gas boiler networks, gas power generation pipe networks, industrial kiln combustion control, low-pressure gas-liquid mixed transmission, and various industrial safety protection systems. This series of valves utilizes a semi-direct acting (also known as lift-type direct acting) control mechanism and belongs to the normally closed automatic valve type. Its core advantage lies in the perfect integration of the zero-pressure differential startup characteristic of direct acting valves and the fluid dynamic assistance characteristic of pilot valves. When the electromagnetic coil is de-energized, under the rigid compression action of the return spring force, the pilot hole remains closed, and the medium enters the cavity above the main valve core (diaphragm or piston) through the fluid channel. Under the combined action of the main spring force and the gas system's own pressure, the sealing assembly is tightly pressed against the main valve seat, achieving absolutely reliable, zero-leakage airtight shut-off. When the electromagnetic coil is energized, a customized electromagnetic assembly instantly generates a powerful electromagnetic attraction force that first opens the pilot hole, and pressure in the cavity above the main valve core quickly relieves to the outlet end through the pilot hole. Simultaneously, the moving iron core of the electromagnet directly pulls up the main valve core assembly through a specialized mechanical linkage lift structure. In extreme working conditions where the system pressure differential is 0bar (such as zero pressure differential, vacuum, or system startup without pressure), the electromagnetic force can directly and rigidly pull open the main valve port, achieving millisecond-level rigid actuation and precise switching. When a weak pressure differential exists in the system, the main valve port is fully opened through the collaborative thrust generated by the electromagnetic attraction force and the medium pressure differential, restoring ultra-large flow unhindered passage. Once the coil is de-energized, the electromagnetic field disappears, and the valve core assembly resets and locks at high speed within milliseconds under the drive of the main spring force, completing a rapid and rigid safety shut-off.Product Image:ZCM Automatic Solenoid Valve for Gas and Low-Pressure Gas-Liquid Feature Semi-direct acting zero-pressure differential drive, perfectly solving actuation lag pain points under low-pressure and zero-pressure conditions: Traditional pilot valves must rely on a starting pressure differential of no less than 0.3-0.5bar under large-bore conditions. The ZCM series adopts a semi-direct acting mechanism, achieving rigid mechanical opening and closing across the full pressure range of 0 to 4bar (whether absolute vacuum, zero pressure, or low-pressure fluctuations). The actuation is crisp and neat, and the response time is shortened to the millisecond level, perfectly meeting the rigorous requirements of gas safety shut-off for rapid cutting. Lift linkage wide-cavity flow channel design, providing excellent ultra-large flow and low fluid resistance performance: Targeting the characteristic of media such as gas and coal gas requiring massive flow accumulation through the valve in a short time under low-pressure states, the internal flow channel of the ZCM series adopts a large-channel, low fluid resistance structure. The semi-direct acting structure ensures that the valve port can be opened completely and thoroughly, and its flow capacity (Cv value) is significantly superior to that of ordinary industrial valves of the same specification, greatly reducing the pressure loss when the medium flows through the valve. High-grade airtight composite sealing pair, providing long-lasting zero internal leakage protection for inflammable and explosive gases: In view of the extremely high permeability and danger of media such as gas and coal gas, the main seal of the valve selects specialized high-elastic, wear-resistant, and hydrocarbon medium corrosion-resistant composite hard rubber or Viton. It absolutely never deforms, hardens, or cracks under high-frequency and powerful mechanical impacts, ensuring a tight fit and long-lasting zero leakage under 4bar pressure. Full coverage of brass/stainless steel/cast iron materials, seamlessly matching diversified industrial pipeline needs: Product specifications extend all the way from DN10 to DN100.

The ZCM series direct acting automatic gas and low-pressure gas-liquid solenoid valve (nominal diameter ranging from DN15 to DN200) is a high-security, heavy-duty fluid control device specially designed and developed for automated pipeline control of low pressure, atmospheric pressure, vacuum, and large flow fluids. As a core execution element in low-pressure industrial gas pipe networks and urban gas emergency safety shut-off loops, this series features deep structural optimization targeting low pressure below 4bar (0.4MPa), zero-pressure conditions, and large-bore fluid transmission. It focuses on solving common industry pain points under ultra-low pressure environments, such as sluggish actuation, pilot holes being easily clogged by medium scaling, and the extreme sealing tightness requirements for highly hazardous media like gas. The series offers multiple premium valve body materials including brass, SS304, and SS316 stainless steel. Small-bore valves utilize G/NPT thread connections, while large-bore valves adopt international standard flange connections, perfectly matching gas boiler networks, centralized gas supply safety shut-offs, industrial kiln combustion control, low-pressure water treatment environmental protection systems, and various vacuum gas-liquid control engineering. This series of valves utilizes a pure direct acting control mechanism and belongs to the normally closed automatic valve type. Its core advantage lies in the fact that its action is completely independent of the medium pressure differential inside the pipeline, possessing a genuine zero-pressure differential rigid switching characteristic. When the electromagnetic coil is de-energized, the high-elasticity return spring applies direct force through the main valve shaft, driving the large-diameter sealing core downward rapidly to press it firmly against the main valve seat. Under the support of the spring's rigid force, absolutely reliable, zero-leakage physical shut-off is achieved. When the electromagnetic coil is energized, a customized high-power electromagnetic assembly instantly generates a powerful electromagnetic attraction force. This attraction force directly and rigidly overcomes the internal main spring resistance and the heavy weight of the large-diameter sealing assembly through the moving iron core, pulling open the valve core directly as a whole. The main valve port opens instantly, and the medium restores large-flow unhindered passage. Within the full series working pressure range of 0 to 4bar, whether the pipeline is in an absolute vacuum state, zero-pressure state, or low-pressure fluctuating condition, the opening and closing of the valve are directly determined by electromagnetic force and spring force. The actuation is crisp and neat, and the response time is shortened to the millisecond level, perfectly eliminating the common industry problem where traditional pilot valves fail to open or close tightly due to insufficient pressure differential.Product Image:ZCM Automatic Solenoid Valve for Gas and Low-Pressure Gas-Liquid Feature Pure direct acting zero-pressure differential drive structure, ensuring rigid action stability under ultra-low pressure and vacuum conditions: Traditional pilot solenoid valves must rely on a starting pressure differential of no less than 0.3-0.5bar under large-bore conditions. The ZCM series adopts a pure direct acting mechanism, achieving rigid mechanical opening and closing across the full pressure range of 0 to 4bar. Whether in a zero-pressure differential state, gravity gravity-flow pipelines, or system negative pressure vacuum conditions, it can achieve millisecond-level rapid response without any actuation lag. Straight-through large channel anti-clogging design, demonstrating extremely high tolerance to fine medium impurities: Since the micron-level pilot small holes and complex piston guiding surfaces of traditional pilot solenoid valves are eliminated, the ZCM series has open internal flow channels and a direct sealing stroke. When the medium carries trace amounts of silt, metal shavings, or scaling particles, the direct acting structure is highly resistant to jamming and clogging, significantly improving the continuous running life of the system under poor water quality or harsh industrial gas environments. SS304/SS316 and premium brass multi-material bodies, completely matching corrosion and safety ratings: Targeting the corrosiveness requirements of different industrial fluids and specialized gases on materials, the entire series offers premium H59 brass, SS304 stainless steel, and SS316 stainless steel with superior resistance to chloride ion corrosion.

The precise thread engagement force and sturdy flange sealing faces can perfectly resist the fluid shearing force and external pipeline knocking generated at the instant of switching in low-pressure large-flow pipelines, eliminating any trace external leakage and ensuring the safety of highly hazardous media such as gas.

The SLDF series semi-direct acting underwater solenoid valve (nominal diameter ranging from DN15 to DN200) is a high-grade, fully waterproof fluid control device specially developed for various waterscape fountains, running fountains, musical fountains, water parks, water treatment environmental protection engineering, and automated control systems that require long-term immersion in underwater working environments. As a core executive element in underwater fluid loops, this series features deep structural optimization targeting common industry pain points caused by long-term underwater immersion, such as coil burnout due to water ingress, high-frequency rapid switching requirements of fountain systems, and the inability of large-bore pipelines to open under zero-differential or low-pressure states. The series offers multiple valve body materials including brass, stainless steel, PA66 engineering plastics, and cast iron. Small-bore valves utilize G/NPT thread connections, while large-bore valves adopt high-strength flange connections, perfectly matching various waterscape arts and industrial water control projects both domestically and internationally. This series of valves utilizes a semi-direct acting (also known as lift-type direct acting) control mechanism and belongs to the normally closed automatic valve type. Its core advantage lies in the perfect integration of direct-acting and pilot-operated controls, possessing the rigid characteristic of zero-differential startup. When the electromagnetic coil is de-energized, the pilot hole remains closed under the action of the return spring force, and the medium enters the cavity above the main valve core through the fluid channel. Under the combined action of the main spring force and water system pressure, the diaphragm or piston assembly is tightly pressed against the main valve seat, achieving absolutely reliable, zero-leakage shut-off. When the electromagnetic coil is energized, a specially customized waterproof coil generates a powerful electromagnetic attraction force that first opens the pilot valve port, and pressure in the cavity above the main valve core begins to relieve. Simultaneously, the moving iron core of the electromagnet directly lifts the main valve core assembly upward through a specialized mechanical linkage structure. Even in an extreme zero-pressure state where the system pressure differential is 0bar (no fluid pressure), the electromagnetic force generated by the coil can directly and rigidly pull open the main valve port, achieving millisecond-level response speeds and 100% precise actuation. When a pressure differential exists in the system, the main valve port is fully opened through the collaborative thrust of electromagnetic force and fluid pressure differential, restoring large-flow unhindered passage. Once the coil is de-energized, the electromagnetic field disappears, and the valve core assembly resets at high speed within milliseconds, completing a rapid and rigid cut-off cycle to ensure that the fountain water column achieves a crisp, drip-free, and perfect visual effect.Product Image:SLDF Underwater Solenoid Valve FeatureSemi-direct acting zero-differential drive, millisecond-level response perfectly matching high-frequency fountain control: Traditional pilot valves must rely on a working pressure differential to operate, making them prone to actuation lag or failure under working conditions where fountain systems start frequently and water pressure is unstable. The SLDF series adopts a semi-direct acting structure, capable of achieving rapid response within 0.1 seconds across the full pressure range of 0 to 8bar (whether vacuum, zero pressure, or low pressure). The water column cuts off cleanly and neatly, perfectly meeting the rigorous requirements of musical fountain high-frequency switching. Special epoxy resin overall encapsulated coil, ensuring long-lasting and safe IP68 underwater submersible sealing performance: As a specialized underwater valve, the internal coil is tightly wound with high-insulation enameled wire, and the entire series of coils utilizes high-density epoxy resin for fully hardened, one-piece monolithic encapsulation, strictly avoiding assembly with plastic shells. Its dustproof and waterproof rating reaches the highest international IP68 standard, capable of withstanding long-term deep water immersion and water flow impacts, possessing excellent moisture resistance, anti-leakage, and anti-aging performance to ensure absolute electrical safety at waterscape performance sites. Multi-material valve bodies and large-span specification configuration, seamlessly matching all-scenario water environment engineering: Product specifications cover a massive span from DN15 to DN200, and valve body materials provide brass, high-quality stainless steel, PA66 engineering plastics, and heavy-duty cast iron. The PA66 material is anti-aging and highly cost-effective, while the brass and stainless steel materials have excellent anti-scouring performance. Targeted selection can be made based on tap water, river water, landscape water, or specialized water with micro-corrosivity. Both thread and flange interfaces are fully available. Fluid mechanics wide-cavity body design, ensuring ultra-large flow performance and absolutely zero internal leakage: Targeting the characteristic of waterscape engineering requiring massive flow accumulation in a short time to generate high water columns, the internal flow channel of the SLDF series adopts a low-resistance streamlined design, and its flow capacity significantly leads ordinary industrial valves. Valve port seals select highly elastic, wear-resistant, and low-temperature resistant specialized hard rubber or composite materials, which never deform or wear under high-frequency powerful impacts, ensuring zero leakage during long-term operation.

The YSP series pilot piston-type stainless steel high-pressure solenoid valve (nominal diameter ranging from DN15 to DN50) is a high-end fluid control device specially designed and developed for medium-to-high pressure and large-flow fluid automated pipeline control. As a core control executive element in large-bore industrial pipeline loops, this series features deep structural optimization targeting 50bar (5MPa) working pressure and large-bore working conditions. It focuses on solving common industry pain points under high-frequency switching, such as main seal erosion and wear, valve core jamming, and the tendency of traditional diaphragm structures to tear and fail under high pressure. The entire series comes standard with high-specification SS304 stainless steel bodies, utilizes advanced piston sealing assemblies, and offers two highly reliable interface types: G thread and NPT thread. It is widely used in medium-to-high pressure cleaning equipment, factory centralized gas supply systems, water treatment networks, hydraulic control base machines, and various gas and liquid automated control engineering. This series of valves utilizes a pilot piston-type control mechanism and belongs to the normally closed automatic valve type. Its core advantage lies in the ingenious utilization of the medium's own pressure differential fluid dynamics to drive the large-bore main piston, thereby greatly reducing the power consumption of the electromagnetic coil. When the electromagnetic coil is de-energized, the pilot hole remains closed under the action of the return spring force. The medium enters the cavity above the main piston through the fluid channel, forming a balanced or top-high-bottom-low pressure distribution across the upper and lower ends of the piston. Under the combined sealing action of the main spring force and the medium system pressure, the piston assembly is tightly pressed against the main valve seat, achieving absolutely reliable, zero-leakage shut-off. When the electromagnetic coil is energized, the customized coil instantly generates a strong electromagnetic attraction force that first opens the pilot hole. At this moment, the medium in the cavity above the main piston quickly relieves pressure to the outlet end through the pilot hole. Since the inlet end of the pipeline bears a system pressure of no less than 0.5bar, a distinct pressure differential is instantly formed between the upper and lower sides of the main piston. The upward thrust generated by this pressure differential directly overcomes the main spring resistance and the piston's dead weight, rapidly pushing the main piston upward. The main valve port is instantly fully opened, and the medium restores large-flow, unhindered passage. Once the coil is de-energized, the electromagnetic field disappears, the pilot hole closes at high speed, and pressure rebuilds above the main piston, driving the piston downward rapidly to reset and lock, completing a rapid and rigid cut-off cycle.Product Image:YSP 2/2-Way Piston Type High Pressure Solenoid Valve FeaturePilot piston low-power structure, perfectly achieving a balance between large bore and 50bar pressure: Traditional direct-acting valves can hardly counteract 50bar pressure under large-bore (above DN15) conditions. The YSP series adopts a pilot piston mechanism, perfectly utilizing the fluid's own energy, so that it only needs to be configured with a conventional power consumption electromagnet to easily control large-diameter high-pressure media. This greatly reduces energy consumption during long-term operation while ensuring a large flow rate (high Cv value). SS304 all-stainless steel piston structure, excellent yield resistance and anti-scouring performance: Targeting the scouring force and cavitation generated when 50bar medium-high pressure fluid flows through large-diameter valve ports, the entire series of valve bodies, pilot valve cores, and main piston assemblies are precisely manufactured from high-quality SS304 stainless steel. The stainless steel piston, paired with high-performance wear-resistant ring guiding, possesses extremely high yield strength and hardness, perfectly eliminating the common phenomenon in traditional large-bore valves where the valve cannot close tightly due to microscopic body deformation or piston jamming. Heavy-duty piston assembly supplemented by composite seals, completely replacing easily damaged and torn diaphragm structures: Under the impact of 50bar pressure and DN15~50 large-bore conditions, traditional rubber diaphragms are highly prone to fatigue tearing. The YSP series adopts a rigid stainless steel piston structure throughout, and the main seal uses special hard composite materials, which can withstand high-frequency mechanical impacts and fluid shocks for a long time, significantly extending the product's service life and reducing maintenance costs.

The YSI series pilot piston-type stainless steel high-pressure solenoid valve (nominal diameter ranging from DN15 to DN50) is a high-end automated control device specially developed for medium-to-high pressure and large-flow fluid transmission pipelines. As a core executive element in large-bore high-pressure pipeline systems, this series features deep structural optimization targeting common industry pain points under 100bar (10MPa) high static pressure and large-bore working conditions, such as external packing leakage, main seal tearing and destruction caused by large-flow high-velocity scouring, and valve failure to actuate due to insufficient electromagnetic force. The entire series comes standard with high-specification SS304 stainless steel bodies, utilizes a heavy-duty piston guiding structure, and offers two highly reliable interface types: G thread and NPT thread. It is widely used in large high-pressure cleaning pump stations, centralized gas supply networks, hydraulic stations, and various industrial automated large-flow fluid control loops. This series of valves utilizes a pilot piston-type control mechanism and belongs to the normally closed automatic valve type. Its core advantage lies in the ingenious utilization of the medium's own pressure differential fluid dynamics to drive the large-bore main piston. When the electromagnetic coil is de-energized, the pilot hole remains closed under the action of the return spring force. The medium enters the cavity above the main piston through the fluid channel, forming a balanced or top-high-bottom-low pressure distribution across the upper and lower ends of the piston. Under the combined sealing action of the main spring force and the 100bar medium pressure, the large-bore stainless steel piston is tightly pressed against the main valve seat, achieving absolutely reliable, zero-leakage shut-off. When the electromagnetic coil is energized, a customized high-power coil instantly generates a strong electromagnetic attraction force that first opens the pilot hole. At this moment, the medium in the cavity above the main piston quickly relieves pressure to the outlet end through the pilot hole. Since the lower side of the piston still bears the high pressure from the inlet end, a huge pressure differential is instantly formed between the upper and lower sides of the main piston. The upward thrust generated by this pressure differential directly overcomes the main spring resistance and the piston's dead weight, rapidly pushing the large-bore main piston upward. The main valve port is instantly fully opened, and the medium restores large-flow, unhindered passage. Once the coil is de-energized, the electromagnetic field disappears, the pilot hole closes at high speed, and pressure rebuilds above the main piston, driving the piston downward rapidly to reset and lock, completing a rapid and rigid cut-off cycle.Product Image:YSI 2/2-Way Piston Type High Pressure Solenoid Valve FeaturePilot piston large-bore low-power structure, perfectly balancing high pressure and large flow: Traditional direct-acting valves cannot counteract 100bar ultra-high pressure under large-bore (above DN15) conditions. The YSI series adopts a pilot piston mechanism, perfectly utilizing the fluid's own energy, so that it only needs to be configured with a conventional power consumption electromagnet to easily control high-pressure media up to 100bar. This greatly reduces electrical energy consumption and coil temperature rise while ensuring a large flow diameter of DN15~50. SS304 all-stainless steel heavy-duty piston assembly, powerful yield resistance and anti-scouring performance: Targeting the extreme scouring force and cavitation damage generated when 100bar high-pressure fluid flows through large-diameter valve ports, the entire series of valve bodies, pilot valve cores, and main piston assemblies are precisely manufactured from high-quality SS304 stainless steel. The stainless steel piston, paired with high-performance wear-resistant guide rings, possesses extremely high yield strength and hardness, never undergoes microscopic deformation under high pressure, and perfectly eliminates the phenomena of piston jamming or incomplete closure caused by deformation. Special high-pressure composite seal combined with fluid buffer design, multiplying large-bore valve lifespan: Targeting the severe "liquid hammer (water hammer)" phenomenon that high-pressure large-bore valves are extremely prone to generate at the instant of opening and closing, this series has undergone precise fluid mechanics optimization for the main cavity and pilot flow channels. An internal buffer damping channel is provided to effectively slow down the impact of sudden pressure changes on the pipeline, protecting the long-term structural integrity of downstream equipment, pipelines, and the solenoid valve's own main seal. International standard industrial high-pressure threads, ensuring absolutely long-lasting and safe system connection: The product provides G and NPT industrial high-pressure threads. The thread processing accuracy reaches the micron level, capable of withstanding severe pipeline vibration and thermal expansion and contraction under 100bar high pressure conditions.

The YSE-A series pilot-operated stainless steel ultra-high pressure solenoid valve (nominal diameter ranging from DN10 to DN25) is a high-end, ultra-high pressure fluid control device specially developed for ultra-high pressure, large-flow fluid transmission and extremely severe operating conditions. As a core shut-off element in ultra-high pressure automated pipeline systems, this series features deep structural optimization targeting common industry pain points under 700bar (70MPa) ultra-high static pressure and large-bore working conditions, such as the inability to open under low pressure differentials, valve core deformation under high-pressure shocks, and seal erosion under large flow rates. The entire series comes standard with high-specification SS304 stainless steel bodies and offers two highly reliable interface types: G thread and NPT thread. It is widely used in high-pressure hydrogen storage and transportation, ultra-high pressure hydraulic pump stations, aerospace ground testing, and high-end industrial cleaning systems. This series of valves utilizes a pilot-operated control mechanism and belongs to the normally closed automatic valve type. Its core advantage lies in the innovative zero-differential pilot drive structure, which perfectly combines the rigid control of electromagnetic force with the fluid dynamics of the medium's own pressure differential. When the electromagnetic coil is de-energized, the pilot valve port remains closed under the action of the return spring force. The medium enters the cavity above the main piston through the fluid channel, forming a balanced or top-high-bottom-low pressure distribution across the upper and lower ends of the piston. Under the combined sealing action of the main spring force and the 700bar ultra-high medium pressure, the main piston is tightly pressed against the main valve seat, achieving absolutely reliable, zero-leakage high-pressure shut-off. When the electromagnetic coil is energized, a specially customized high-power, super-magnetic coil instantly generates a powerful electromagnetic attraction force that first pulls open the pilot valve port. Thanks to its special forced-lift mechanism, even in an extreme zero-pressure state where the system pressure differential is 0bar, the electromagnet can directly lift the main piston mechanically via a linkage, ensuring 100% precise actuation. When a pressure differential exists in the system, the medium in the cavity above the main piston quickly relieves pressure to the outlet end through the pilot hole, utilizing the huge pressure differential thrust of the fluid to push the main piston to the fully open position, restoring highly efficient, large-flow passage. Once the coil is de-energized, the electromagnetic field disappears, and the pilot hole and main piston reset downward at high speed within milliseconds, completing a rapid and rigid high-pressure cut-off cycle.Product Image:YSE-A 2/2-Way Normally Closed Ultra-High Pressure Solenoid Valve FeatureForced pilot-operated zero-differential startup, perfectly compatible with the full pressure range from 0 to 700bar: Traditional pilot valves must rely on a working pressure differential under large-bore conditions, while conventional direct-acting valves cannot handle large bores under 700bar ultra-high pressure. The YSE-A series ingeniously combines the advantages of both by adopting a unique forced-linkage pilot structure. Whether the system is in a zero-differential vacuum state without pressure or an ultra-high pressure environment up to 700bar, the valve can achieve millisecond-level response speeds, completely solving the industry pain point where ultra-high pressure test pipelines cannot start under low or zero pressure states. SS304 all-stainless steel heavy-load structure, powerful yield resistance and anti-scouring performance: Internal components are precisely manufactured from high-quality SS304 stainless steel to withstand the destructive scouring force and cavitation damage generated when 700bar extreme high-pressure fluid flows through large-bore valve ports of DN10~25. The stainless steel valve body possesses extremely high yield strength and never undergoes any microscopic deformation under 700bar ultra-high pressure, perfectly eliminating the common phenomena of incomplete closure or piston jamming caused by body deformation. Super-magnetic high-power coil configuration, ensuring rigid and stable output torque: Since opening a large-bore pilot hole under 700bar pressure requires overcoming massive surface tension and high-pressure clamping force, the YSE-A series is equipped with an ultra-high-power coil customized through precise electromagnetic field simulation. The coil interior is tightly wound with high-temperature resistant pure copper enameled wire. Although the output actuation torque is extremely powerful, it adopts advanced heat dissipation and low-power temperature rise design, supporting all-weather, high-frequency continuous energization. Micron-level high-pressure thread standards, ensuring absolutely long-lasting and safe system connection: The product provides G and NPT industrial ultra-high pressure threads. The thread processing accuracy reaches the micron level, capable of withstanding severe pipeline vibration, pressure pulsations, and thermal expansion and contraction under 700bar ultra-high pressure conditions.

The YSE series pilot-operated stainless steel high-pressure solenoid valve (nominal diameter ranging from DN6 to DN25) is a high-end, high-pressure fluid control device specially developed for medium-to-high pressure and large-flow gas transmission, hydraulic control systems, high-pressure cleaning equipment, and automated pipelines carrying various light and low-viscosity oils (viscosity less than or equal to 20cst). As a core executive element in high-pressure automation control loops, this series features deep structural optimization targeting common industry pain points under 160bar (16MPa) high static pressure and large-bore working conditions, such as valve failure to actuate due to insufficient electromagnetic force and seal erosion caused by excessive flow velocity. The entire series comes standard with high-specification SS304 stainless steel bodies and offers two highly reliable interface types: G thread and NPT thread. This series of valves utilizes a pilot-operated control mechanism and belongs to the normally closed automatic valve type. Distinct from direct-acting solenoid valves that rely on electromagnetic force to directly lift the valve core, the core advantage of pilot-operated valves lies in the ingenious utilization of the medium's own pressure differential to drive the main valve core. When the electromagnetic coil is de-energized, the pilot hole is closed under the action of the return spring force. The medium enters the cavity above the main piston through the fluid channel, forming a balanced or top-high-bottom-low pressure distribution across the upper and lower ends of the piston. Under the combined action of the main spring force and the medium pressure, the main piston is tightly pressed against the main valve seat, achieving absolutely reliable, zero-leakage shut-off. When the electromagnetic coil is energized, it generates an electromagnetic attraction force that first opens the pilot hole. At this moment, the medium in the cavity above the main piston quickly relieves pressure through the pilot hole. Since the lower side of the piston still bears the high pressure from the inlet end, a clear pressure differential is instantly formed between the upper and lower sides of the main piston. The upward thrust generated by this pressure differential directly overcomes the main spring resistance and the piston's dead weight, rapidly pushing the main piston upward. The main valve port is instantly fully opened, and the medium restores large-flow, unhindered passage. Once the coil is de-energized, the pilot hole closes within milliseconds, pressure rebuilds above the main piston, driving the main piston downward at high speed to reset and lock, completing a rapid and rigid cut-off cycle.Product Image:YSE 2-Way 2-Position Pilot-Operated Stainless Steel High Pressure Solenoid Valve FeaturePilot-operated pressure differential drive structure, achieving low-power actuation under large-bore and high-pressure states: Traditional direct-acting high-pressure valves require extremely massive electromagnetic coils to counteract high pressure at large bores (above DN6). The YSE series adopts a pilot-operated mechanism, perfectly utilizing the fluid's own energy, so that it only needs to be configured with a conventional power consumption electromagnet to easily control high-pressure media up to 160bar. This greatly reduces energy consumption and coil heat generation while ensuring a large flow rate. SS304 all-stainless steel piston structure, powerful yield resistance and anti-scouring performance: Targeting the extreme scouring force and cavitation damage generated when 160bar high-pressure fluid flows through large-bore valve ports, the entire series of valve bodies, pilot valve cores, and main piston assemblies are precisely manufactured from high-quality SS304 stainless steel. The stainless steel valve body possesses extremely high yield strength and hardness, never undergoes microscopic deformation under high pressure, and perfectly eliminates the common phenomenon in high-pressure valves where the valve cannot close tightly due to body deformation or piston jamming. Unique buffer and anti-cavitation design, effectively extending service life under high-pressure and large-flow conditions: Targeting the liquid hammer (water hammer) phenomenon and cavitation damage that high-pressure large-bore valves are extremely prone to generate at the instant of opening and closing, this series has undergone precise fluid mechanics optimization for the flow channels between the pilot hole and the main cavity. By rationally designing buffer damping, the impact of sudden pressure changes on the pipeline is slowed down, protecting both downstream equipment and the solenoid valve's own seals. International high-pressure thread standards, ensuring absolutely long-lasting and safe system connection: The product provides G and NPT industrial high-pressure threads. The thread processing accuracy reaches the micron level, capable of withstanding severe pipeline vibration and thermal expansion and contraction under ultra-high pressure conditions. It achieves seamless original-position tightening with various domestic and overseas high-pressure pump stations and high-pressure hydraulic base machines, eliminating common hazards of high-pressure pipelines such as interface bursting and micro-leakage.

The YSE Series Direct Acting Stainless Steel High Pressure Solenoid Valve (with nominal orifice sizes spanning from DN1 to DN5, equivalent to 1mm to 5mm internal sizing) is an ultra-high-pressure automatic control valve engineered for high-pressure gas distribution networks, high-pressure hydraulic control systems, high-pressure washing machinery, aerospace ground test manifolds, and automated pipelines transporting light low-viscosity oils (viscosity less than or equal to 20 cst). Serving as a critical final execution element within high-pressure circuits, this series features advanced structural hardening specifically optimized to solve industry vulnerabilities under 300 bar (30 MPa) ultra-high static pressures, such as external packing leakage, valve needle deformation, and electromagnetic actuation failure caused by excessive high-pressure resistance. All models feature a premium SS304 stainless steel body with high-integrity G or NPT threaded connection profiles. The YSE series operates as a Normally Closed (NC) valve utilizing a true direct-acting electromagnetic configuration.Unlike pilot-operated valves that require a minimum working pressure differential between the upstream and downstream pipelines to stroke the valve, the direct-acting mechanism operates completely independently of system pressures. Even under zero differential pressure (0 bar), the valve guarantees precise, millisecond-level actuation. When the electromagnetic coil is de-energized, the heavy-duty internal plunger is driven downward by a high-tension compressed return spring, pushing a high-hardness stainless steel valve needle (or custom ultra-high pressure composite disc) directly onto the micro-orifice seat. At this stage, even when subjected to an upstream static pressure of 300 bar, the valve uses direct mechanical force and micro-engineered hard-seating boundaries to block the process medium, achieving a tight shutoff. When the electromagnetic coil receives an electrical current, a high-power, custom-wound solenoid coil instantly generates a high-density magnetic field. This electromagnetic force directly overcomes the resistance of the high-tension return spring, the weight of the plunger assembly, and the heavy high-pressure holding force exerted by the 300 bar medium on the valve needle face. The plunger is pulled upward in a crisp, linear motion, lifting the valve needle off the micro-seat. Because the electrical force acts directly upon the sealing needle without secondary pilot chambers, the micro-orifice opens completely, allowing full fluid transmission. When power is disconnected, the magnetic field collapses within milliseconds, and the high-tension spring forces the needle back down to complete the high-pressure isolation cycle.Product Image:YSE Direct Acting Stainless Steel High Pressure Solenoid Valve FeaturePure Direct-Acting Configuration for Instant Zero-Differential Activation: Conventional pilot-operated high-pressure valves require a minimum differential pressure of 0.5 bar to open, and their small internal pilot channels are highly susceptible to fluid shear erosion at high pressures. The YSE series eliminates all pilot chambers and micro-orifices, connecting the solenoid plunger directly to the valve needle. Whether operating in a vacuum condition with zero line pressure or under an ultra-high-pressure state of 300 bar, the valve delivers millisecond response times, resolving a common industry challenge in low-pressure and zero-pressure calibration testing loops. SS304 Stainless Steel Construction for High Structural Yield and Erosion Resistance: To withstand the extreme fluid scouring, cavitation, and structural stresses generated when 300 bar media flows through a micro-orifice, the valve body and all moving components are machined from high-grade SS304 stainless steel. This alloy offers excellent yield strength, preventing micro-deformation under pressure and eliminating the seat jamming and internal leakage common in lower-grade high-pressure hardware. The material's natural resistance to pitting makes it compatible with light lubricating oils, high-pressure water, and high-purity gases. High-Wattage Solenoid Coil for Rigid Actuation and Thermal Stability: Because a direct-acting mechanism must pull directly against the high surface tension and mechanical clamping forces generated by 300 bar pressures, the YSE series is equipped with a custom high-wattage solenoid coil. Wound with high-temperature pure copper magnet wire, the coil utilizes advanced thermal-dissipation geometry to support continuous duty (100 percent ED) and frequent cycling with a minimal operational temperature rise, ensuring consistent magnetic torque output. Precision High-Pressure Threading for Secure System Integration: Available with either G parallel or NPT tapered high-pressure industrial threads machined to micron-level tolerances. This threading preserves connection integrity against intense pipeline vibrations, mechanical shock, and thermal expansion cycles. It integrates directly into ultra-high-pressure gas cylinder manifolds, high-pressure hydraulic power units, and industrial test equipment, eliminating connection ruptures and micro-leakage risks.
