A hydraulic control arrangement for hydraulic consumer includes a multiple position valve having a control slide movable by proportional magnets between a neutral position and a plurality of working positions, in which the magnets may be remote controlled from an analog desired value signal and in which a stop valve is provided in a control circuit leading from the consumer to an over-pressure valve, which in turn is connected, upstream of the multiple position valve, parallel to the consumer between a pressure conduit connected to a source of pressure and a return conduit connected to a tank.
