Product Description

^{The ZZY type self-operating pressure regulating valves are ingeniously designed to require no external energy, utilizing the energy of the controlled medium itself as a power source. By ingeniously incorporating an actuator, these valves adeptly manage the valve core position, dynamically altering the flow area to precisely adjust the flow rate. This sophisticated mechanism ensures the stabilization of pressure both before and after the valve, making it an exemplary choice for precise pressure management.}

 

<sup>Exhibiting unparalleled sensitivity and impeccable sealing, these valves offer minimal pressure fluctuation, making them the quintessential solution for automatic control applications. They are extensively utilized in the realms of pressure reduction and stabilization, as well as pressure relief and stabilization of gas, liquid, and steam mediums, across a diverse range of industrial equipment.


Within this series, our company proudly offers products that are meticulously categorized based on the valve core type into single-seat (P), sleeve (M), and double-seat (N) structures. Additionally, based on the actuator type, they are elegantly classified into three distinct types: diaphragm type, piston type, and bellows type, catering to a wide array of application needs.</sup>

<sup>Operating Principle

In scenarios where downstream pressure needs to be expertly controlled, the ZZYP-B type valve excels in pressure reduction and stabilization. Should the downstream pressure exceed the meticulously set value, the valve demonstrates its brilliance by closing and ultimately shutting off. Conversely, when the pressure dips below the set threshold, the valve remains open, adeptly compensating for the pressure.

Conversely, when tasked with controlling upstream pressure, the ZZYP-K type valve is a bastion of safety pressure relief and stabilization. When the upstream pressure daringly rises above the set value, the valve responds astutely by opening and fully engaging. However, should the pressure fall below the desired level, the valve strategically remains closed, ensuring optimal performance.</sup>

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

Our innovative ZZYP-II series nitrogen sealing device represents a groundbreaking, self-operating micro-pressure control system, meticulously developed in-house. Predominantly utilized to consistently maintain the pressure of protective gases like nitrogen atop storage tanks, it deftly prevents direct contact between tank materials and air, thereby curtailing evaporation, thwarting oxidation, and safeguarding container integrity.</sup>

<sup>Perfectly suited for the gas sealing protection systems of expansive storage tanks, this product epitomizes energy efficiency and operational sensitivity, delivering dependable performance with effortless operation and maintenance. Its widespread application spans vital industries such as petroleum and chemical engineering, attesting to its versatile utility.

Ingeniously designed to function without external energy sources, this model operates seamlessly without reliance on electricity or gas, rendering it a marvel of convenience, energy efficiency, and cost-effectiveness.</sup>
 

<sup>The nitrogen sealing device streamlines nitrogen supply and vent pressure settings effortlessly, thriving under continuous production conditions. Boasting a pressure detection diaphragm with a large effective area and a setting spring with minimal stiffness, it operates with unmatched sensitivity, ensuring smooth and efficient device performance.

To uphold storage tank safety, installing a breather valve at the top is imperative. Acting solely as a safety mechanism, the breather valve significantly minimizes the wear and tear associated with the frequent operation of nitrogen supply and vent valves, a common issue in conventional nitrogen sealing devices.</sup>
