ABSTRACT:
A rotary ball for a fluid control valve controlling a fluid stream with a spherical ball control member and a spherically shaped dome containing a plurality of apertures at the ball inlet bore end. The fluid stream is dissipated and broken up into smaller streams by being forced through the apertured dome. One or more apertured discs can be mounted in the bore to obtain the desired valve capacity and noise attenuation. A domed apertured plate may also be used at the bore outlet end. Substantially constant noise attenuation is obtained over the full travel of the valve from the initial open position to the fully opened position.
