Product Description

Super High Pressure Control Valve for Medium Pressure Gas and Steam
Introducing the ZZY type self-operating pressure regulating valves, these innovative devices eliminate the need for external energy sources by harnessing the power of the controlled medium itself. Through an intelligently designed actuator, these valves dynamically adjust the valve core position, altering the flow area to precisely regulate and stabilize the pressure before or after the valve, ensuring seamless flow management.



 
With remarkable sensitivity and excellent sealing capabilities, these valves minimize pressure fluctuations, making them indispensable in automatic control systems. Whether for pressure reduction and stabilization or pressure relief in various gas, liquid, and steam mediums, they excel across a diverse range of industrial equipment applications.


Our meticulously engineered product line encompasses a variety of valve core structures, including single-seat (P), sleeve (M), and double-seat (N) designs. Additionally, the robust series offers three actuator types: diaphragm, piston, and bellows, providing tailored solutions for specific industrial needs.

Operating Principle

For downstream pressure control (ZZYP-B type), the valve adeptly handles tasks of pressure reduction and stabilization. When downstream pressure exceeds the desired set value, the valve initiates closure, eventually sealing off to maintain optimal conditions, while it remains open to compensate when pressure is below the target.

In contrast, for upstream pressure control (ZZYP-K type), safety pressure relief and stabilization are key functions. As upstream pressure surpasses the preset threshold, the valve efficiently opens, ensuring full pressure relief, whereas it remains closed when pressure stays below the designated level.

The nitrogen sealing device simplifies nitrogen supply and pressure setting, capable of functioning seamlessly under continuous production. Featuring a large diaphragm area for pressure detection and a spring with minimal stiffness, it ensures sensitive operation and smooth performance.

For enhanced storage tank safety, a breather valve is essential atop the tank. This safety-focused component prevents the wear from frequent opening and closing of conventional nitrogen supply and vent valves, ensuring consistent and reliable tank pressure management.
