Abstract
A control valve having a closing element, mounted in a housing between an inlet side and an outlet side and rotatable about an axis between a first and second end positions, and a passage channel through the closing element perpendicularly with respect to the rotational axis. The channel has inlet and outlet openings and connects the inlet side to the outlet side in the first end position, disconnects the inlet side from the outlet side in the second end position, and permits an increasing throughflow of a medium during the transition from the second end position into the first end position with a characteristic curve. Low valve noise is achieved because of the shape, size and configuration of the inlet and outlet openings of the passage channel and the configuration of walls of the passage channel without steps and edges.
