ABSTRACT:
A method for attenuating a medium flow passing through a valve provided with a flow passage. Into the valve, a substantially ball-like or ball-segment shaped or conical or cylindrical plug-like closure member has been fitted turnably. The attenuating of the flow has been arranged as taking place in both flow directions mainly in the passage in the closure member or in a bore passing through the closure member. The attenuating effect is increased as the valve is being closed and the attenuating effect is correspondingly reduced as the closure member is being turned towards the open position. In the passage in the closure member or in the bore passing through the closure member, the length of the path of flow of the pressure medium is increased and the direction of the flow of the pressure medium is alternated. The more the valve is being closed, the longer becomes the path of flow of the pressure medium in the bore or passage in the closure member and, correspondingly, the higher becomes the number or changes in direction of the pressure medium flow within the range of the passage or bore in the closure member.
