とする圧力制御弁。 A valve spool that increases or decreases the hydraulic pressure of both output ports depending on the axial movement position is slidably fitted inside a valve body equipped with two output ports, and a valve spool for each output port is attached to both ends of the valve spool. A feedback hole for introducing feedback hydraulic pressure is provided, a pilot piston is slidably fitted into the feedback hole, and pressing means for pressing and moving the valve spool are provided at both ends of the valve body, and each of the pressing means 1. A pressure control valve characterized in that a stopper member is interposed between a movable part and a pilot piston opposing the movable part to restrict movement of the pilot piston in the direction of the opposing movable part.
