Working principle of pilot type pressure reducing valve

2023-12-28

Pilot type pressure reducing valve (pilot type pressure reducing valve working principle) The working principle of the pilot type pressure reducing valve: the pilot type pressure reducing valve by the valve body, the main spring, the main valve core, the main valve seat, the piston, the pilot spring, the pilot valve core, the pilot valve seat, the pilot piston and the adjustment spring and other components. Tighten the adjusting screw, compress the adjusting spring, and open the pilot valve core. The medium enters the piston from the inlet side. Because the piston area is larger than the main valve core area, the piston is pushed down to open the main valve. The pressure of the spring changes the opening of the pilot valve, thereby changing the pressure above the piston, and controlling the opening of the main valve core to keep the pressure behind the valve constant.
