とする圧力制御用バルブ。 A valve body with two ports, one of which is an inlet and the other is an outlet, a control spool that is slidably provided on the valve body to open and close the two ports, and a control spool that opens and closes the two ports. The control spool is provided with a solenoid that can control the suction force that suctions the control spool in a direction, and a biasing means that biases the control spool in a direction that closes the two ports against the suction force of the solenoid and the pressure of the fluid. , the pressure control is configured to control the pressure of the fluid by controlling the load that urges the control spool in the direction of closing the two ports by the suction force of the solenoid. Valve for.
