ABSTRACT:
A ball valve assembly and method in which a ball valve is rotatable in a conduit section to and from an open position in which at least a portion of a bore in the valve registers with the inlet and the outlet of the conduit section to permit the flow of the fluid through the conduit section. An insert is disposed in the bore and has a plurality of through passages formed therein for reducing the noise caused by the fluid flow though the ball valve and is operable over a relatively wide range of pressure drops and flow rates.
