Abstract
A valve, in particular a 4/2-way slide valve (), includes a valve piston (), which is guided in a longitudinally movable manner in a valve housing (), for selectively connecting and disconnecting fluid connections in the valve housing (), such as a pressure supply connection (P), a tank connection (T), and two utility connections (A, B). A magnetic system (), to which current can be supplied, controls the valve piston (). When no current is supplied to the magnetic system (), the control pressure at one of the utility connections (A, B) can be set, in particular limited, by a control device () arranged in the valve housing.
