The pressure reducing valve belongs to the pilot piston type pressure reducing valve. It consists of two parts: the main valve and the pilot valve. The main valve is composed of parts such as valve seat, main valve disc, piston, spring, etc. The pilot valve is mainly composed of parts such as valve seat, valve disc, diaphragm, spring, and regulating spring. By adjusting the spring pressure to set the outlet pressure, using the diaphragm to sense the change in outlet pressure, and driving the piston to adjust the size of the flow area at the throttle position of the main valve through the opening and closing of the pilot valve, the pressure reducing and stabilizing function is achieved.
