Abstract
A valve includes a valve housing (), which has at least one service connection (A, B), a pressure supply connection (P) and a return connection (T). In the valve housing (), a control slide (STS) is guided so as to be movable longitudinally to control these individual connections. The supply pressure, which is applied to the pressure connection (P) to control a consumer (), connected to the service connection (A; B), is guided across at least one control side () of the control slide (STS) via an orifice plate () and a control channel (). The control side () is positioned in a control chamber () in the valve housing () such that it can move. The control chamber () is connected to the return connection (T) via an additional orifice plate ().
