ABSTRACT:
A device with a valve for setting the flow of a flow medium, which has a passage channel with an inlet opening and with an outlet opening for the flow medium, and with a tongue-like valve element, which is arranged in the passage channel. The valve element is adjustable in a rotatably movable manner with an actuating device between two end positions. The device is adapted to users who need the flow medium at different pressure levels by providing a discharge opening branching off from the passage channel. The discharge opening is provided with a diaphragm opening having a predetermined gap geometry. The discharge opening with diaphragm opening is arranged in the range of pivoting of the valve element such that the discharge opening is closed in one of the end positions and the passage channel is switched essentially in the direction of flow at the same time.
