Product Description

Reliable Self-Operating Control Valve for High Pressure Liquid Applications
The ZZY type self-operating pressure regulating valves are ingeniously designed to function without the need for any external energy source. These innovative valves utilize the intrinsic energy of the controlled medium as their power source, effectively introducing an actuator to deftly manage the valve core position. This spectacular mechanism adjusts the flow area, thus seamlessly regulating the flow rate to ensure the utmost stabilization of pressure before or after the valve.



 
Renowned for their remarkable sensitivity, impeccable sealing, and minimal pressure fluctuation, these valves find their superior application across a multitude of industries. They are expertly crafted for automatic control processes aimed at pressure reduction and stabilization, or pressure relief and stabilization for gas, liquid, and steam mediums within diverse industrial apparatus.


Our esteemed product line is meticulously categorized into single-seat (P), sleeve (M), and double-seat (N) configurations, based on the valve core type. Furthermore, the series is thoughtfully divided into three actuator types: diaphragm, piston, and bellows, offering a tailored solution for every unique industrial need.

Operating Principle

In scenarios where downstream pressure control is required (ZZYP-B type), the valve expertly performs pressure reduction and stabilization. Should the downstream pressure exceed the set threshold, the valve naturally inclines to close, eventually sealing shut. Conversely, if the downstream pressure dips below the desired value, the valve remains open to adeptly compensate and uphold the pressure.

For upstream pressure control needs (ZZYP-K type), the valve functions as an efficient safety pressure relief and stabilization tool. When upstream pressure surpasses the set threshold, the valve effortlessly opens, ensuring a full opening. If the upstream pressure falls beneath the set value, the valve prudently stays closed, assuring optimal control.

Featuring an intuitive nitrogen supply and vent pressure setting, this device can seamlessly operate under continuous production conditions. Its pressure detection diaphragm boasts a generous effective area, while the setting spring is delicately calibrated for minimal stiffness. The result is a highly sensitive operation that ensures smooth, uninterrupted performance.

To fortify storage tank safety, the installation of a breather valve at the tank's summit is imperative. This valve serves purely as a safety mechanism, effectively preventing the frequent and wear-inducing opening and closing of traditional nitrogen supply and vent valves, thereby extending their lifespan and reliability.
