In the electromagnetic proportional solenoid valve configured to stroke, the coil current is a pulsating current driving current, and the initial setting load by the return spring is applied to the valve spool until the amplitude of the pulsating driving current reaches a certain amplitude. An electromagnetic proportional solenoid valve characterized by being set to a load value that does not operate.
