Product overview
This series of pressure reducing valve belongs to the pilot piston type pressure reducing valve. It consists of main valve and pilot valve. The main valve is mainly composed of valve seat, main valve disc, piston, cylinder liner, spring and other parts. The pilot valve is mainly composed of valve seat, valve disc, diaphragm, spring, adjusting spring and other parts. The outlet pressure is set by adjusting the spring pressure, the diaphragm is used to sense the change of the outlet pressure, and the pilot valve is opened and closed to drive the piston to adjust the size of the flow area of the throttling part of the main valve, so as to realize the function of decompression and voltage regulation.
