イロット流体圧力が設定可能なパイロット弁を備えたパ
イロット流路に接続したことを特徴とする圧力制御弁。A valve body that is equipped with a supply port, an output port, and an exhaust port has a valve body that opens and closes a supply valve seat and an exhaust valve seat, and a feedback chamber that communicates with the output port and a pilot chamber that communicates with the output port of the high pressure selection valve. The regulating part is configured to be opened and closed by a pressure-receiving body that can be displaced by a pressure difference, and prevents the valve body from being displaced in the direction of opening the exhaust valve seat as pressure increases in the feedback chamber. It is constituted by a locking rod that protrudes to a position that prevents displacement of the pressure receiving body when introduced, and is configured so that the drive chamber and one input port of the high pressure selection valve can be switched and communicated with the atmosphere and the output port by a release valve. A pressure control valve characterized in that the other input port of the high-pressure selection valve is connected to a pilot flow path equipped with a pilot valve in which a pilot fluid pressure can be set.
