Description: This additional control unit is a 5/4-way valve that is used to manually control cylinders and hydraulic motors. It has slide-sealed consumer connections A and B.
This means that only a small amount of internal leakage is permitted at high loads. The consumer connections A and B are located at the top and bottom of the housing. The device has a detent position in the lifting position, which is equipped with a hydraulically automatic limit switch. There is no limit switch integrated in the detent lowering position. If you switch further via the lowering position, the detent floating position is switched on (consumer connections A and B are connected to each other for the return flow). The floating position can be used as a detent lowering position with both double-acting and single-acting lifting cylinders. The additional control unit can be switched from double-acting to single-acting and vice versa.
