1. A valve device, comprising:
a valve housing with fluid ports disposed in the valve housing;
a valve piston being displaceable along a longitudinal axis thereof between at least first and second travel positions in the valve housing connecting or separating the fluid ports in a fluid-conveying manner; and
first and second latches being at opposite ends of the valve piston and latching the valve piston in the first and second travel positions, individual latching parts of each of the first and second latches, when actuated by respective external forces, being movable to individual latching positions spatially different from one another with respect to the longitudinal axis of the valve piston, the individual latching positions differing from one another both in axial directions and in radial directions of the longitudinal axis of the valve piston, the first and second latches having first and second control bodies, respectively, at the opposite ends of the valve piston; and
a rod system drive having a control rod passing through the valve piston and alternatively actuating the first and second latches.
