Product Description
Introducing the ZZY type self-operating pressure regulating valves: a marvelous innovation that eliminates the need for external energy. These valves ingeniously utilize the energy of the controlled medium as their power source, ingeniously incorporating an actuator to govern the valve core position. This sophisticated mechanism adjusts the flow area, thereby masterfully controlling flow rates to ensure absolute pressure stability before or after the valve.
Experience unparalleled performance with our valves that boast sensitive operation, exceptional sealing capabilities, and minimal pressure fluctuation. These attributes make them the ideal choice for automatic pressure reduction and stabilization, or pressure relief and stabilization of gases, liquids, and steam across a myriad of industrial equipment, ensuring optimal efficiency and reliability.
Our exceptional series of products is meticulously engineered and categorized based on valve core types into single-seat (P), sleeve (M), and double-seat (N) structures. Furthermore, they are expertly classified into three actuator types: diaphragm, piston, and bellows, each designed to meet diverse operational demands with precision and efficacy.
Operating Principle
Discover the remarkable functionality of the ZZYP-B type valve when employed for downstream pressure control. Its adept functions include pressure reduction and stabilization. Should the downstream pressure exceed the pre-set desired value, the valve instinctively tends to close, eventually sealing shut. Conversely, if the downstream pressure falls below the desired threshold, the valve remains open, seamlessly compensating to maintain pressure equilibrium.
Harness the safety benefits of the ZZYP-K type valve for upstream pressure management. This valve excels in safety pressure relief and stabilization. When upstream pressure surpasses the set desired value, the valve adeptly opens and remains fully open. Conversely, when pressure is below the set point, the valve stays closed, safeguarding the system with precision.
Our innovative ZZYP-II series nitrogen sealing device represents a breakthrough in self-operating micro-pressure control systems, proudly developed in-house. It specializes in maintaining a constant protective gas pressure-typically nitrogen-at the top of storage tanks, preserving the integrity of stored materials by preventing material evaporation and oxidation, and ensuring safety by averting direct air contact.Ideal for safeguarding gas sealing systems in large storage tanks, this product stands out for its energy efficiency, sensitive operation, and reliable performance. It is celebrated for its ease of operation and maintenance, making it indispensable in industries such as petroleum and chemical engineering, where reliability and efficiency are paramount.
Our device shines as a paradigm of convenience and sustainability. It impressively operates without reliance on external energy such as electricity or gas, making it an energy-saving and cost-effective solution that champions both practicality and environmental stewardship. Engineered for seamless integration, the nitrogen sealing device enables effortless nitrogen supply and pressure vent settings, functioning flawlessly even under continuous production conditions. With a diaphragm boasting a large effective area and a delicately tuned setting spring, it operates with heightened sensitivity and unparalleled smoothness.
For the ultimate in storage tank safety, a breather valve installation at the tank's apex is essential. This crucial component serves purely as a safety mechanism, judiciously preventing the frequent, wear-prone opening and closing of nitrogen supply and vent valves typical in conventional nitrogen sealing systems, thereby extending the lifespan of your equipment.Test and Detection Equipment
