Product Description

High Pressure Self-Operating Control Valve for Industrial Gas Systems
Introducing the ZZY type self-operating pressure regulating valves, a marvel of energy efficiency and innovation. These sophisticated valves cleverly utilize the energy from the controlled medium itself, eliminating the need for any external power source. By ingeniously introducing an actuator, they seamlessly control the valve core position, thus elegantly altering the flow area. This smart adjustment ensures a steady and reliable flow rate to maintain consistent pressure either before or after the valve.



 
These valves are designed with precision and excellence, boasting an impressively sensitive operation, superior sealing capabilities, and minimal pressure fluctuation. They are the epitome of reliability and are indispensable in the realm of automatic control systems. Perfectly suited for the reduction and stabilization of pressure or for pressure relief across gas, liquid, and steam mediums, they find their home in a variety of industrial equipment.


Our distinguished series offers an array of products tailored to meet specific needs. These are categorized by the valve core type into single-seat (P), sleeve (M), and double-seat (N) structures. Furthermore, the series provides versatility with actuators available in diaphragm type, piston type, and bellows type, catering to diverse operational requirements.

Operating Principle

When tasked with regulating downstream pressure (ZZYP-B type), these valves perform with precision to achieve pressure reduction and stabilization. Should the downstream pressure surpass the desired set value, the valve intuitively begins to close, eventually ceasing flow altogether. Conversely, if the downstream pressure dips below the set value, the valve remains open to proficiently maintain the desired pressure.

In scenarios requiring control of upstream pressure (ZZYP-K type), these valves excel in providing safety pressure relief and stabilization. When upstream pressure exceeds the set benchmark, the valve intelligently opens, ensuring full relief. If the upstream pressure remains below the set value, it remains closed, offering steadfast control and protection.

The nitrogen sealing device is designed for effortless nitrogen supply and vent pressure settings, even under continuous production conditions. With a pressure detection diaphragm of a large effective area and a spring with minimal stiffness, it operates with remarkable sensitivity and smoothness.

To fortify the safety of storage tanks, it is crucial to install a breather valve at the tank's top. This valve serves an essential safety role by preventing the frequent and wear-intensive opening and closing cycles of nitrogen supply and vent valves, a common issue in traditional nitrogen sealing devices.
