Product Details
Pressure reducing valve belongs to the pilot piston type pressure reducing valve. By the main valve and pilot valve two parts. Main valve mainly by the valve seat, the main valve plate, piston, spring and other parts of the composition. The pilot valve is mainly composed of valve seat, valve, diaphragm, spring, adjusting spring and so on. By adjusting the spring pressure to set the outlet pressure, the use of the diaphragm sensing outlet pressure change, through the pilot valve opening and closing the main valve throttle position of the flow area of the size, to achieve the function of pressure relief.
