させたことを特徴とする電磁比例制御弁。 An electromagnetic proportional system in which the opening area of the fluid passage is continuously controlled to open and close according to the input current using a spool that operates by moving a plunger using an electromagnetic force proportional to the input current and the biasing force of a spring. In the control valve, a pressure equalization hole passing through the center of the plunger and the spool and a space formed by the plunger, the spool, and the body are connected to a communication path that crosses the pressure equalization hole provided in the plunger or the spool. An electromagnetic proportional control valve characterized in that it communicates with the valve.
