Abstract
Disclosed is a valve device, comprising at least one valve piston arranged in a valve housing in a longitudinally displaceable manner, which valve piston is moved by means of a drive in conjunction with the assigned drive train and interconnects individual fluid ports present in the valve housing in a fluid-conveying manner or separates them from one another. A sensor device monitors the respective positions of the drive train and thus the respective positions of the valve piston in the valve housing.
