PURPOSE:To permit use of an electromagnetic valve in liquid, by covering a solenoid portion of the valve with a water tight cover and filling the internal space of the cover with insulating oil or operating liquid. CONSTITUTION:A spool 3 is engaged with a hollow portion 2 of a casing 1 of an electromagnetic valve. A body 4 and a water tight insulating cover 5 which is concentrically inserted with respect to the body 4 are attached to one side portion of the casing 4. A stationary magnet piece 9 is fixed in the water tight cover 5 and a movable magnet piece 11 is connected to an end of a rod 31 and provided with a travelling hole 12 so that the operating liquid charged in the water tight insulating cover 5 can flow through the travelling hole 12 when the movable magnet piece 11 moves. With this arrangement the valve can be used independently under light pressure.
