A solenoid valve has a housing having work, pressure, and tank connectors. An armature is movably arranged in the housing and cooperates with a coil. A slide is moveably arranged in the housing and has a hydraulic chamber connected to the work connector and connectable to the pressure connector. A plunger is positioned between the armature and the slide. The armature acts on the plunger which acts on the slide for moving the slide against a counter force. The plunger has a cross-section and the slide has a piston surface cooperating with the plunger, wherein the cross-section is smaller than the piston surface. In another embodiment, the slide has a first end, loaded by a supply pressure of the pressure connector, and a second end, loaded by a return pressure, so that the slide is hydraulically tensioned by the supply pressure and the return pressure.
