Abstract
A valve has a control slide () guided in a valve housing () so as to be longitudinally movable. The control slide selectively connects a plurality of fluid connection points (P, T, A, B) in the valve housing () to each other in a fluid-conducting manner or disconnects the fluid connection points from each other, and can be electrically controlled by a stepper motor (). The control slide () can be actuated by an emergency device () in the event of a malfunction or failure.
