Abstract
A valve device has a valve housing (), in which fluid ports (P, A, T) are provided and in which at least one valve piston () can be moved longitudinally. The valve piston either separates at least two of the fluid ports (P, A, T) from one another or interconnects them as a function of its travel position. At least one latching device () is provided for each valve piston () for the detachable fastening of the respective valve pistons () in one of its travel positions. Each latching device has at least one latching means (), which can be brought into a latching position (). As part of the respective latching devices () for detachably fastening the respective valve pistons (), at least one control body () t can be moved independently of the respective valve pistons (), which control body is set up such that, in at least one blocking position, it prevents the relevant latching means () disposed in the latching position () from leaving the latching position () by blocking the latching means ().
