An electromagnetic valve for controlling fluid flow to and from a load includes a valve stem movable, upon excitation of an armature, to lift a valve body from a first valve seat against pressure of a pressure fluid to enable flow of the pressure fluid to the load. The valve stem has a blocking portion remote from the valve body and which is lifted from a second valve seat located adjacent to the armature, in an unexcited condition of the armature, by the valve body to enable flow of fluid from the load past the second valve seat through at least one bore formed in the armature, to a reservoir.
