摘要： A valve is described including a valve seat defining a first port and a second port and an angularly movable valve member having a first face and a second face. The valve member is movable between a closed position in which the first face thereof, or a valve element associated therewith, closes at least one of the ports and an open position. The valve member defines a first flow passage and a second flow passage, each flow passage communicating with a chamber defined, at least in part, by the second face of the valve member. At least the first flow passage defines or includes a flow director to impart a circumferential or tangential component to the fluid flow therethrough.
