1. Valve and valve device comprising a valve of that type. 2. The invention relates to a valve comprising a valve housing (33), which has at least one service connection (A, B), a pressure supply connection (P) and a return connection (T) and in which valve housing (33) a control slide (STS) is guided so as to be movable longitudinally in order to control these individual connections. The valve is characterised in that the supply pressure, which is applied to the pressure connection (P) in order to control a consumer (10, 12) connected to the service connection (A; B), is guided across at least one control side (56) of the control slide (STS) via an orifice plate (54) and a control channel (50), the control side (56) being positioned in a control chamber (58) in the valve housing (33) such that it can move and the control chamber (58) being connected to the return connection (T) via an additional orifice plate (59).
