御弁。 A pressing force of a solenoid proportional to the current is applied in the direction of movement of one of the spool valves, and a feedback pressure is applied to a stepped pressure receiving part formed at one end of the spool valve and having a different diameter from the sliding part of the spool valve. In a pressure control valve that generates a control pressure proportional to a solenoid current in an output circuit by movement of the valve, a first throttle is provided on a path between the stepped pressure receiving part and the output circuit, and the first throttle and A pressure control valve characterized in that a second throttle is provided on a path communicating between a stepped pressure receiving part and a drain passage.
