ABSTRACT:
A valve includes a body having a valve element positioned therein. The valve element includes a bore therethrough, which is selectively alignable with bores through the valve body. As the valve element is moved to position the valve element bore in an askew position with respect to the valve body bores, flow eddies or turbulence may form and result in vibration and/or noise. The valve includes a plurality of diffusers which break up the flow to reduce the noise and/or vibration. Additionally, a secondary flow passage may be disposed between the valve element bore and the outlet bore of the valve body, to permit a portion of the flow through the valve to pass therethrough as the valve element is rotated to throttle the flow through the valve.
