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