Product Description

^{ZZY type self-operating pressure regulating valves are ingeniously designed to function without the need for external energy sources. These advanced valves utilize the inherent energy of the controlled medium as their power source, seamlessly integrating an actuator to deftly manage the position of the valve core. This sophisticated mechanism alters the flow area, allowing for precise adjustment of the flow rate, thereby achieving a stable pressure environment either before or after the valve.}

 

<sup>Boasting sensitive operation, exceptional sealing capabilities, and maintaining minimal pressure fluctuations, these valves are the epitome of reliability in automatic control systems. They excel in pressure reduction and stabilization or pressure relief and stabilization across a variety of industrial equipment, handling gas, liquid, and steam mediums with unparalleled efficiency.


Our company's series of products are meticulously crafted into single-seat (P), sleeve (M), and double-seat (N) designs, meticulously tailored to the valve core type. Further, they are categorized into three distinct actuator types: diaphragm, piston, and bellows, offering a tailored solution for every need.</sup>

<sup>Operating Principle

For downstream pressure control (ZZYP-B type), the valve's primary function is pressure reduction and stabilization. When downstream pressure surpasses the desired threshold, the valve instinctively moves towards closure, eventually sealing off. Conversely, when downstream pressure drops below the set value, the valve opens, skillfully compensating for pressure variations.

In upstream pressure control (ZZYP-K type) applications, the valve serves as a guardian for pressure relief and stabilization. When upstream pressure exceeds the predetermined set value, the valve intuitively reacts by opening fully, ensuring safe pressure levels. Should the pressure fall below the set value, the valve remains securely closed.</sup>

<sup>ZZYP-II Type Self-Operating Pressure Regulating Valve with Commander

The ZZYP-II series, a pinnacle of innovation, showcases a self-operating micro-pressure control system for nitrogen sealing, exclusively developed by our company. This device maintains a steady, constant pressure of protective gas, typically nitrogen, atop storage tanks, safeguarding the contents from atmospheric exposure, preventing evaporation and oxidation, and upholding container integrity.</sup>

<sup>Perfectly suited for gas sealing protection systems in extensive storage tanks, this product embodies energy efficiency and precision operation. Renowned for its dependable performance and simple maintenance, it finds extensive application across the petroleum and chemical engineering sectors.

Ingeniously crafted to operate without external energy sources, this system functions autonomously, eliminating the need for electricity or gas. Its design emphasizes convenience, energy conservation, and cost-effectiveness.</sup>
 

<sup>The nitrogen sealing device facilitates effortless nitrogen supply and vent pressure adjustments, seamlessly adapting to continuous production environments. Equipped with a large effective area pressure detection diaphragm, a delicately tuned setting spring with minimal stiffness, it guarantees sensitive operations and unwavering reliability.

For the utmost safety of storage tanks, installing a breather valve at the tank's apex is essential. This safety-focused valve prevents the frequent, wear-inducing opening and closing of nitrogen supply and vent valves, a common issue in conventional nitrogen sealing devices.</sup>
