Product Description

Self-Operating Control Valve for Super High Pressure Liquid and Gas
The ZZY type self-operating pressure regulating valves are the epitome of innovation, eliminating the need for any external energy sources. By harnessing the energy within the controlled medium itself, these valves ingeniously utilize an actuator to position the valve core. This precision modification of the flow area ensures an optimal adjustment of the flow rate, effectively stabilizing pressure either before or after the valve, as required.



 
Renowned for their remarkably sensitive operation, these valves boast excellent sealing capabilities and ensure minimal pressure fluctuation. They are indispensable in the realm of automatic control, expertly managing tasks such as pressure reduction and stabilization, or pressure relief and stabilization across gas, liquid, and steam mediums in diverse industrial environments.


Our meticulously crafted series offers a selection of valves based on the valve core type, including single-seat (P), sleeve (M), and double-seat (N) structures. Additionally, the product range includes actuator variations such as diaphragm type, piston type, and bellows type, each tailored to meet specific operational demands.

Operating Principle

For adept control of downstream pressure, consider the ZZYP-B type. Designed for pressure reduction and stabilization, when downstream pressures surpass the desired set value, the valve naturally trends towards closure, ultimately shutting off. Conversely, should downstream pressure dip below the target, the valve remains open to maintain equilibrium.

When tasked with upstream pressure management, the ZZYP-K type excels, functioning as a bastion of safety pressure relief and stabilization. In instances where upstream pressures exceed the set value, the valve instinctively opens wide. Meanwhile, when upstream pressure remains below the set threshold, the valve stays securely closed to maintain safety.
