This invention relates to a control valve which comprises a first and a second flow channel (), a valve chamber () and a closing member (), from which a shaft () extends. A flow connection is established in the control valve through the inner part of the chamber (). The flow connection into the chamber () and the one out of the chamber () are constricted at all openings (A, A, A) when the closing member () is turned about the rotation axis () in the chamber ().

Control valve

A valve and method for adjusting the flow of a valve and for forming a turbulence in the flow. The flow is led tangentially from the inlet passage (2) into the space inside the valve body (1) in such a way that a turbulent flow is formed inside the valve body, outside the closure member. The flow volume is adjusted before the flow is brought into turbulence.
