る圧力制御弁。[Scope of Claim for Utility Model Registration] The solenoid is slidably provided in the pilot sliding hole, is pressed by the solenoid in the direction of increasing the pilot fluid pressure, receives feedback fluid pressure in the direction of decreasing the pilot fluid pressure, and reduces the pressing force of the solenoid. A pilot spool that can control pilot fluid pressure in proportion to do,
a main spool capable of controlling the hydraulic pressure of the output circuit in proportion to the pilot hydraulic pressure, the pilot sliding hole being drilled through the main spool at an axial center position; A pressure control valve characterized by having a pilot spool inside the main spool.
