A valve device having a valve housing (10), in which fluid ports (P, A, T) are provided and in which at least one valve piston (12, 14) can be moved longitudinally, which 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, and having at least one latching device (16, 18) for each valve piston (12, 14) for the detachable fastening of the respective valve pistons (12, 14) in one of its travel positions, which latching device has at least one latching means (20), which can be brought into a latching position (22), which is characterized in that, as part of the respective latching devices (16, 18) for detachably fastening the respective valve pistons (12, 14), at least one control body (24) that can be moved independently of the respective valve pistons (12, 14) is provided, which control body is set up such that, in at least one blocking position, it prevents the relevant latching means (20) disposed in the latching position (22) from leaving the latching position (22) by blocking the latching means (20) is disclosed.
