The YSZ Series Normally Closed Bi-stable Latching Pulse Solenoid Valve is a premier pilot-operated pulse-driven control valve specifically engineered and highly customized for small-to-medium flow pipeline precision control, industrial environmental dust collector pulsing systems, and various energy-saving fluid integration equipment. Covering a comprehensive size spectrum from DN10 to DN50, this series boasts an ultra-compact, streamlined geometric profile. While significantly optimizing spatial utilization, it fully supports and complies with high-precision G thread and NPT thread connection standards, greatly facilitating quick on-site installation, quick assembly, and seamless adaptation within diverse international piping networks.

The internal flow channels and sealing pairs have undergone deep fluid-dynamics optimization specifically calibrated for low-to-high differential pressure working conditions. The valve delivers exceptional responsiveness, minimal pressure drop, and rapid open/close cycling within a wide and reliable 0.3 to 16 bar pressure range. To withstand various rigorous industrial operating environments, the valve bodies are available in three core material choices: high-quality forged Brass, premium anti-corrosive SS316 Stainless Steel, or engineered plastic PA66, ensuring universal compatibility with water, fluid liquids, air, neutral gases, and low-viscosity light oils. The most distinct technological edge of this series lies in its advanced bi-stable latching pulse actuation mechanism. This technology not only substantially reduces the cumulative energy consumption of the electrical control system but also achieves absolute "zero heat generation" during continuous high-frequency operations, making it an ideal, high-efficiency control component for small-to-medium automated fluid loops and modular skid designs.

Feature

Compact Footprint & Multiple Thread Standards: Custom-tailored for DN10 to DN50 small-to-medium pipelines with a highly compact geometry that drastically minimizes the required installation envelope. Full compliance with internationally accepted G and NPT thread standards ensures an instantaneous, hassle-free match with domestic and global industrial automated piping layouts.

Bi-stable Latching with Zero Thermal Rise & Energy Savings: Utilizing industry-leading pulse excitation control, the electromagnetic coil is energized only for a fraction of a second during the switching stroke. It consumes absolutely zero continuous electrical power to maintain its state. This mechanism fundamentally eliminates the risk of coil temperature rise, thermal overload, and electrical burnout typical of traditional continuous-duty solenoid valves, significantly prolonging the service life of electrical components.

Superior High-Pressure Wide-Range Performance: The internal pilot flow paths and flexible composite diaphragm structure are geometrically balanced with high precision, allowing a pressure-bearing capacity up to 16 bar. Boasting an ultra-low starting pressure differential, the valve secures clean, instantaneous opening and closing strokes even at a microscopic minimum pressure differential of just 0.3 bar, completely resolving the chronic issue of sluggish operation found in conventional pilot valves under low pressures.

Premium Materials for Varied Operating Conditions: The forged Brass variants offer outstanding cost-performance and remarkable machining accuracy for standard water and air loops. The SS316 Stainless Steel models are custom-built for highly aggressive or ultra-clean environments, providing exceptional resistance against localized pitting corrosion. The PA66 engineered plastic variant provides excellent insulation, a lightweight structure, and high wear resistance to meet diverse chemical compatibility requirements.

All-Weather Freeze Resilience & Structural Integrity: Engineered with a wide operational envelope spanning from -20 to 65 ℃, the specialized elastomeric seals and robust valve body resist hardening, crystallization, and cracking under freezing winter outdoor environments or overnight sudden temperature drops, ensuring long-term leak-proof structural integrity.
