Product Description

High Pressure Self-Operating Control Valve for Efficient Liquid Flow
ZZY type self-operating pressure regulating valves are marvels of innovation, uniquely designed to eliminate the need for external energy sources. These sophisticated valves harness the energy from the controlled medium itself, employing a dynamic actuator that regulates the valve core position. This remarkable mechanism alters the flow area, thereby deftly adjusting the flow rate to maintain stable pressure levels whether before or after the valve, ensuring seamless operation.



 
Renowned for their ultra-sensitive operation and exceptional sealing capabilities, these valves exhibit minimal pressure fluctuation. They have become indispensable in the realm of automatic control systems for their prowess in pressure attenuation and stabilization, as well as pressure relief and stabilization of gas, liquid, and steam mediums. Widely employed across a multitude of industrial equipment, they epitomize reliability and efficiency.


Our company's product line in this series features an array of sophisticated designs tailored to meet diverse industrial needs. Choose from single-seat (P), sleeve (M), and double-seat (N) structures based on the valve core type, and explore three distinct actuator types: diaphragm, piston, and bellows. Each variant is expertly crafted to deliver optimized performance and adaptability.

Operating Principle

For applications involving downstream pressure control (ZZYP-B type), this valve excels in pressure reduction and stabilization. When downstream pressure surpasses the predetermined value, the valve ingeniously closes, eventually sealing off. Conversely, if the pressure dips below the set threshold, the valve remains open, ensuring pressure equilibrium.

In scenarios that necessitate upstream pressure control (ZZYP-K type), the valve's role shifts to providing safety pressure relief and stabilization. It skillfully opens when upstream pressure exceeds the defined value, fully opening as needed. When pressure drops below the set value, the valve stays sealed, offering a robust and reliable pressure management solution.

The nitrogen sealing device features intuitive nitrogen supply and vent pressure setting, maintaining optimal function during continuous production. With a large effective diaphragm area for pressure detection and low stiffness setting spring, it operates with remarkable sensitivity, ensuring smooth and efficient performance.

To fortify the safety of storage tanks, a breather valve is essential atop the tank. This valve plays a crucial safety role, preventing the cumbersome and wear-prone cycle of opening and closing nitrogen supply and vent valves encountered in traditional nitrogen sealing systems, thus enhancing longevity and reliability.
