In a damping valve for pressure medium-actuated operating circuits, a spring element is installed between housing, cover and counter-contour. In the opening direction, the spring element is pressed against the counter-contour by the pressure medium flowing through, so that a flow passage cross-section allowing almost unimpeded passage of the pressure medium is obtained. In the opposite direction, the throttling direction, the spring element rests on the cover and blocks the flow of the pressure medium until a well-defined pressure builds up, which lifts the inner side of the spring element from the counter-contour and thus opens a reduced flow passage cross-section.
