配設されたことを特徴とする圧力制御弁。 In a pressure control valve, the valve spool is provided with a feedback means for pushing back the valve spool that has moved in the direction of increasing the output fluid pressure in the direction of decreasing the output fluid pressure, and generates an output fluid pressure proportional to the amount of movement of the valve spool. . A pressure control valve, characterized in that a pressing member is disposed at the shaft end of the valve spool for pushing the valve spool back in the direction of reducing the output fluid pressure when the feedback means is not activated.
