Product Description

^{Our ZZY type self-operating pressure regulating valves redefine efficiency by eliminating the need for external energy sources. Harnessing the intrinsic energy of the controlled medium, these valves ingeniously utilize an actuator to modulate the valve core position, seamlessly adjusting the flow area. This innovative mechanism ensures a stabilized flow rate, maintaining consistent pressure either before or after the valve, depending on the application.}

 

<sup>Featuring exceptional sensitivity and precision, our valves provide a perfect seal and exhibit minimal pressure fluctuation. These attributes make them indispensable in automated systems, facilitating flawless control for pressure reduction, stabilization, and pressure relief across gas, liquid, and steam mediums in a diverse array of industrial operations.


Our extensive range of products is meticulously engineered into three distinct structures based on the valve core type: single-seat (P), sleeve (M), and double-seat (N). Furthermore, they are innovatively categorized by actuator type: diaphragm, piston, and bellows, offering unparalleled adaptability for various industrial applications.</sup>

<sup>Operating Principle

For expert control of downstream pressure, the ZZYP-B type valve offers unparalleled efficiency in pressure reduction and stabilization. Exceeding the set downstream pressure prompts the valve to initiate closure, while pressure below the desired set point ensures the valve remains open, maintaining optimal pressure levels.

Expertly designed for upstream pressure regulation, the ZZYP-K type valve delivers superior safety pressure relief and stabilization. When upstream pressure surpasses the designated threshold, the valve opens fully, ensuring secure pressure levels. Conversely, if the pressure drops below the target, the valve remains securely closed.</sup>

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

Meet the advanced ZZYP-II series nitrogen sealing device, a pioneering self-operating micro-pressure control system developed by our company. Designed to maintain a consistent protective gas pressure atop storage tanks, it effectively prevents contact between stored materials and air, mitigating risks like evaporation or oxidation, thus safeguarding container integrity.</sup>

<sup>This state-of-the-art device is tailor-made for gas sealing protection in large storage tanks. It combines energy efficiency with responsive operation and robust performance, offering straightforward operations and minimal maintenance. Utilized extensively in petroleum and chemical industries, it stands as a hallmark of reliability and innovation.

Operating independently of external energy sources, this system exemplifies convenience and energy conservation, providing a cost-effective solution devoid of the need for electricity or gas.</sup>
 

<sup>The nitrogen sealing device simplifies operation through straightforward nitrogen supply and vent pressure settings, functioning flawlessly even under continuous production conditions. Its large effective diaphragm area and delicate spring stiffness ensure sensitive operation, maintaining seamless and efficient device performance.

To uphold storage tank safety, a breather valve is essential at the tank's apex. This valve functions solely as a safety measure, reducing the wear typically associated with conventional nitrogen sealing devices, and minimizing the frequency of valve operation, thereby prolonging the system's lifespan.</sup>
