ABSTRACT:
A ball valve assembly and method in which a ball valve is rotatable in a conduit section to selectively permit fluid flow through the bore to control the flow of the fluid through the conduit section. An insert is disposed in the valve bore, has a plurality of small-diameter passages and defines, with a portion of the valve, a large-diameter passage extending therethrough. The valve is rotated from its closed position to a first, partially-opened position where the small-diameter passages are in the flow path of the fluid to reduce the flow rate and the noise caused by the fluid flow. The valve can be rotated to a fully-opened position in which the large-diameter passage is in the flow path of the fluid to achieve relatively high flow rates. The insert forms an airfoil surface to prevent separation of the fluid as it passes through the large-diameter passage.
