Self operated pressure reducing valve

The working principle of a self operated pressure reducing valve is mainly to adjust the flow rate of the medium by controlling the opening and closing of the valve body, thereby reducing the pressure of the medium. With the help of the pressure behind the valve and the action of the spring, the opening of the valve disc of the pressure reducing valve is adjusted to maintain the pressure behind the valve within a certain range. Self operated pressure reducing valves come in both diaphragm and piston types, capable of regulating and stabilizing the flow and pressure stability of pipeline equipment behind the valve. The self operated pressure reducing valve produced by Shanghai Meiyanyi Pump Valve operates based on the principle of local resistance changes, balance adjustment using springs, and the energy of the medium itself. It is widely used in various pipeline equipment that requires stable pressure, especially steam pipelines, and has significant energy-saving effects.
