A hydraulic control valve ( 1 ) is assigned to a pressure line ( 13 ) led from a pressure medium source to at least one load. The control valve has a first position in which the pressure line ( 13 ) is pressurized by the pressure medium source and a second position in which the load connected to the pressure line ( 13 ) is depressurized. The control valve ( 1 ) is directed toward the first position by an actuating device ( 17 ) and toward the second position by a restoring device ( 11 ). The control valve ( 1 ) has a safety function such that the pressure line ( 13 ) can be depressurized to a container, irrespective of the position of the control valve ( 1 ). The safety function can be a valve function ( 20 ) integrated in a control slide ( 3 ) of the control valve ( 1 ).
