Pilot operated pressure reducing valve

Pilot operated pressure reducing valve refers to the use of pressure regulating gas or liquid through a conduit and a pilot valve to first send pressure to the spring control chamber to regulate the pressure before and after the valve. When the output pressure of the pressure reducing valve is high or the diameter is large, using a pressure regulating spring to directly regulate the pressure may cause excessive spring stiffness, resulting in large fluctuations in output pressure when the flow rate changes. To overcome these disadvantages, a pilot operated pressure reducing valve can be selected, which supplies pressure regulating gas through a small direct acting pressure reducing valve and uses pressure regulating gas instead of a pressure regulating spring to adjust the output pressure. The design of the pilot operated pressure reducing valve produced by Shanghai Meiyanyi Pump Valve makes it suitable for applications that require remote control or high pressure and large flow.
