OverviewThe U41S Plunger Stop Valve is a special structure stop valve that achieves reliable sealing through the interference fit between the plunger and the sealing ring. Driven by the valve stem, the plunger performs vertical lifting motion within the sealing ring to complete the opening/closing and flow regulation of the pipeline medium. The core of its design lies in replacing the traditional disc with a plunger. The interference fit design between the plunger and the upper and lower elastic sealing rings, combined with the pre-tightening force adjustment of the middle flange bolts, causes the side force generated by the compression of the sealing rings to act on the outer cylindrical surface of the plunger and the bore surface of the valve body. This forms a reliable radial sealing pair, thereby achieving excellent zero-leakage sealing performance. The key components of the valve feature a stainless steel plunger and high-performance non-metallic sealing rings (such as flexible graphite, PTFE composite materials, etc.). The sealing rings possess characteristics of strong resilience, high wear resistance, and high-temperature resistance, maintaining elasticity and sealing performance during long-term use. The valve typically adopts a flanged connection, securely fixed to the pipeline flanges with bolts, offering convenient installation and reliable sealing. The opening and closing of the valve are achieved by turning the handwheel or a matching electric actuator to drive the valve stem, converting rotary motion into the vertical lifting motion of the plunger for smooth and reliable control. This valve combines the leak-free advantages of plunger valves with the quick opening/closing characteristics of stop valves. It is widely used in process pipeline systems in industries such as petroleum, chemical, electric power, metallurgy, pharmaceutical, and heating supply, especially suitable for working conditions involving steam, oil, water, and generally corrosive media where strict sealing performance and frequent operation are required.

The core of its design lies in the presence of a water seal system inside the valve, which can form a stable liquid film sealing ring between the valve disc and the valve seat sealing pair by injecting specific pressure of clean water or softened water, thereby achieving excellent zero leakage sealing effect. The key components of the valve are made of corrosion-resistant and erosion resistant materials, and are designed with enhanced valve disc guidance and sealing surface structure to ensure absolute sealing and operational reliability under harsh working conditions such as high temperature, high pressure, toxic and harmful, flammable and explosive. Valves are usually connected by flanges and firmly fixed to pipeline flanges with bolts. Valves can be driven by manual devices or matching electric/pneumatic devices to convert input force into direct motion of the valve disc, achieving smooth and reliable opening, closing, and regulating control. This valve is designed specifically for process pipeline systems in industries such as petroleum, chemical, metallurgical, and power. It is particularly suitable for working conditions that require absolute cut-off and zero leakage of gas, natural gas, oil and gas, and other hazardous or valuable media.Product drawing of DSJ41H Water-sealed Vacuum Stop Valve feature1. Excellent zero leakage sealing: Adopting a unique water seal system design, a stable liquid film sealing ring is formed between the valve disc and the valve seat sealing pair by injecting clean water or softened water, achieving absolute cut-off and zero leakage sealing, especially suitable for toxic, harmful, flammable, explosive or valuable media.2. Adapt to high pressure, high temperature, and harsh working conditions: The key components of the valve are made of high temperature resistant, erosion resistant, and corrosion-resistant materials (such as hard alloy or stainless steel), with high structural strength and special hardening treatment on the sealing surface, which can operate stably for a long time in high temperature, high pressure, and harsh media containing trace particles.3. Self cleaning and safety protection: The water sealing medium can continuously flush the sealing surface while sealing to prevent scaling, crystallization, or particle deposition, and maintain the cleanliness of the sealing pair; The water seal system can also serve as an isolation barrier, effectively preventing the leakage of hazardous media and enhancing the intrinsic safety of the system.4. Reliable operation and dual control: supports manual, electric or pneumatic drive, with excellent valve stem guidance structure and smooth movement; The water seal system can independently adjust the water pressure to form a sealing force that matches the medium pressure, ensuring reliable sealing of the valve during the opening and closing process and in the fully closed position.5.

System integration and intelligent monitoring: The water seal pressure can be connected to the instrument system for real-time monitoring and alarm; Combined with intelligent actuators, remote monitoring and automatic interlocking control of valve status and water seal pressure can be achieved, which is easy to integrate into the automation management platform and improves process safety and reliability.

OverviewJ941H electric globe valve is a valve that opens, closes, and regulates fluid channels by driving the valve disc vertically up and down along the centerline of the valve seat channel through the valve stem. The sealing pair (valve disc and valve seat) adopts a metal hard sealing structure, usually welded or embedded with hard alloy, which has the characteristics of high hardness, wear resistance, and high temperature resistance. The valve is connected by flanges and fixed to the pipeline flange with bolts. Valves rely on electric devices (usually multi turn electric actuators) to drive the valve stem, converting electrical energy into rotational torque and linear thrust, thereby accurately and reliably controlling the opening, closing, or positioning of the valve disc. This valve is particularly suitable for high-temperature and high-pressure working conditions that require remote automatic control, high-precision regulation, or lack of gas source.J941H electric globe valve Product Diagram feature1. High sealing reliability: Adopting a metal hard sealing structure, the valve disc and seat sealing surface are welded with hard alloy and precision ground to achieve tight metal line sealing under high torque thrust of the electric actuator. The sealing level can reach ANSI Class VI or above, suitable for high temperature, high pressure and zero leakage harsh working conditions.2. Precise control and flexible adjustment: The valve disc moves vertically in a straight line without obstruction, and with high-precision electric actuators and positioning feedback systems, it can achieve precise opening control and stable positioning, meeting the requirements of process automation adjustment.3. High temperature and pressure resistance and erosion resistance: High temperature and pressure bearing valve body materials (such as WCB/WC6/CF8) and hard alloy sealing surfaces are used, which can withstand PN160 pressure and high temperature ≤ 550 ℃, and have good erosion resistance to steam, high-speed fluids, and particulate media.4. High fluid resistance: The valve chamber channel is designed in an "S" shape with a non straight through design, and the flow direction of the medium needs to be reversed. When fully opened, the flow resistance coefficient and pressure loss are higher than those of gate valves and ball valves of the same specification, and the system design needs to consider additional pressure drop.5. Compact structure but high installation space requirements: Compared with butterfly valves and ball valves, globe valves have a larger height and length structure, requiring sufficient installation and maintenance space to be reserved, especially considering the installation position of electric actuators and auxiliary electrical units.6. High integration of intelligent driving: adopting multi turn electric actuators, supporting 4-20mA, bus communication and other control methods, with functions such as torque protection, fault diagnosis, and power-off self maintenance, suitable for non gas source or highly integrated automation systems, supporting remote centralized control and intelligent adjustment.

OverviewThe WJ40Y American standard bellows globe valve is a special valve designed with a metal bellows dynamic seal. The valve disc is driven vertically along the centerline of the valve seat by the valve stem to achieve reliable opening and closing of the pipeline and flow regulation. The core of its design is to use fully enclosed metal bellows components instead of traditional packing boxes, completely isolating the valve stem from the process medium. The elastic deformation of the bellows compensates for the valve stem stroke, thereby completely eliminating medium leakage at the valve stem. The key sealing components of the valve are made of high-quality alloy materials that are corrosion-resistant and erosion resistant. The corrugated pipe is formed by multi-layer lamination process, which has extremely high fatigue life and pressure bearing capacity, ensuring zero leakage sealing and long-term reliable operation under harsh working conditions such as high temperature, high pressure, toxic and harmful, flammable and explosive. The valve strictly follows the American standard specifications such as ASME B16.34, and is connected using RF or RJ flanges. It is firmly fixed to the pipeline flange with bolts. Valves can be driven by manual devices or matching electric/pneumatic devices to convert input force into linear motion of the valve disc, achieving smooth and reliable opening, closing, and regulating control. This valve is designed specifically for process pipeline systems in industries such as petroleum, chemical, pharmaceutical, and energy that require extremely high leak control. It is particularly suitable for steam, toxic gases, volatile liquids, vacuum systems, and other hazardous or environmentally sensitive medium conditions that require absolute no leakage.WJ40Y American standard corrugated pipe globe valve product diagramfeature1. Absolute stem zero leakage seal: Multi layer metal bellows components are used as the core sealing structure to completely isolate the stem from the medium. The corrugated tube undergoes elastic deformation during its travel, completely eliminating the risk of medium leakage caused by wear and aging in traditional packing boxes, and achieving permanent zero leakage at the valve stem.2. Suitable for high temperature, high pressure, and harsh working conditions: The valve body and key sealing components are made of high-quality heat-resistant alloy steel or stainless steel. The corrugated pipe is formed by high-precision hydraulic molding and multi-layer welding, with excellent pressure resistance, temperature resistance, and fatigue resistance. It can operate stably in high temperature, high pressure, thermal cycling, and corrosive media for a long time.3. Double sealing and safety protection: In addition to the main seal of the corrugated pipe, the emergency packing box is still retained as the second sealing barrier. When the corrugated pipe unexpectedly fails, the packing box can temporarily provide a seal to prevent sudden large leakage of the medium, significantly improving the safety margin of system operation.4. Low friction, long lifespan, and easy maintenance: The bellows seal does not require regular compression or replacement of packing, reducing maintenance frequency and cost. The valve stem moves within the bellows without direct friction, with stable operating torque and a service life far exceeding that of traditional packing sealed valves.5. Compact structure and standard compatibility: Strictly designed and manufactured according to American standards such as ASME B16.34, using standard flange connections such as RF and RJ, and installation dimensions fully compatible with international common systems. Compact structure, especially suitable for situations where space is limited or installation height is required.6. Clean and pollution-free with intelligent monitoring: The all metal sealed structure is free of any non-metallic materials, avoiding medium pollution, especially suitable for industries such as pharmaceuticals, food, and high-purity chemicals. It can integrate signals such as valve opening and torque feedback, and work with intelligent actuators to achieve remote monitoring and predictive maintenance of status.
