Product Description

Super High Pressure Control Valve for Reliable Gas and Steam Control
The ZZY type self-operating pressure regulating valves are an innovative marvel that eliminates the need for external energy sources. Harnessing the energy of the controlled medium itself, these valves incorporate an advanced actuator mechanism to adjust the valve core position masterfully. By altering the flow area, they adeptly modulate the flow rate, ensuring stable pressure levels either before or after the valve.



 
These valves are distinguished by their exceptionally sensitive operation, impeccable sealing capabilities, and minimal pressure fluctuation, making them an ideal solution for automatic control systems. They excel in reducing and stabilizing pressure or providing relief and stabilization for gas, liquid, and steam mediums across a wide spectrum of industrial equipment.


Our company's exquisite product line in this series features a versatile range of designs. Options include single-seat (P), sleeve (M), and double-seat (N) structures, tailored to complement the valve core type. The series also offers three actuator types: diaphragm, piston, and bellows, providing a comprehensive selection to meet diverse operational needs.

Operating Principle

In applications where downstream pressure control is required (such as with the ZZYP-B type), the function is twofold: pressure reduction and stabilization. If the downstream pressure exceeds the set value, the valve instinctively moves towards closure, ultimately shutting off. Conversely, when the pressure dips below the target value, the valve remains open to maintain optimal pressure.

For upstream pressure control (ZZYP-K type), the valve operates as a guardian for safety pressure relief and stabilization. Upon exceeding the set pressure, it promptly opens and fully engages to relieve excess pressure. If the upstream pressure falls below the desired level, the valve remains closed, ensuring stability and safety.

Engineered for seamless nitrogen supply and precise vent pressure setting, the nitrogen sealing device is designed to thrive under continuous production conditions. The pressure detection diaphragm's expansive effective area, coupled with its minimal setting spring stiffness, ensures sensitive operation and a smooth, reliable performance.

To bolster the safety of the storage tank, the installation of a breather valve at the tank's summit is obligatory. This valve's singular purpose is to safeguard against frequent, wear-inducing operations of nitrogen supply and vent valves found in traditional sealing systems, thereby enhancing the overall longevity and efficacy of nitrogen sealing devices.
