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.

Valve having a control slide guided in a valve housing so as to be longitudinally movable

A control device, in particular for hydraulically controlling components of mobile working machines, has a pressure supply connection (P) and a tank or return connection (T) in addition to two user connections (A, B). Control and/or regulating valves () are connected between the individual connections (P, T, A, B). Two control lines (C, Z) can control at least one of the control and/or regulating valves. A modular-type functional block () is connected to at least one of the control lines (C, Z).

Control apparatus

A connecting apparatus connects to a main component () having a plurality of mutually adjacent fluid passage points (P', P&#x2032;, P&#x2032;, P&#x2032;n . . . P&#x2032;x). The connecting apparatus has a main body () controlling a fluid flow by a valve. A plurality of further fluid passage points (P, P, P, Pn . . . Px) can be connected to each other in a fluid-conducting manner via the functional component () with assignable fluid passage points in the main component (). One shut-off part, which shuts off the respective fluid passage point (P&#x2032;, P&#x2032;, P&#x2032;n . . . P&#x2032;x&#x2212;1) in the main component () and/or in the fluid passage point remains unaffected by the functional component (). In each case a fluid-conducting connection line () is inside the main body () between the further fluid passage points (P, P, P, Pn . . . Px) and the functional component () and can be shut off by a separate shut-off part, as long as the associated connection to the functional component () remains unused.
