A solenoid that presses both ends of the valve spool with a plunger disposed coaxially with the valve spool, and the pressing force of the solenoid and the reaction piston are In the electromagnetic proportional pressure control valve, the valve spool slides to a position where the feedback hydraulic pressure due to the reaction force is balanced, and an output hydraulic pressure proportional to the electromagnetic force of the solenoid is obtained. The plunger is formed into a cylindrical shape so that they do not interfere in the axial direction, and the plunger is connected to the valve spool without going through the reaction piston, so that the plunger can be directly slid toward the solenoid side with respect to the reaction piston. An electromagnetic proportional pressure control valve characterized by having a regulating stopper.
