Claim Text:
1. A ball valve, comprising: a valve body having a plurality of ports and a valve chamber therebetween, the plurality of ports and the valve chamber defining a fluid flow passage; a valve member disposed within the valve chamber and defining a flow aperture therethrough, the valve member selectively movable within the valve chamber to adjust flow along the fluid flow passage by adjusting the orientation of the flow aperture relative to the plurality of ports; a flow disk carried by the valve body and substantially disposed within the fluid flow passage, wherein the flow disk is operably coupled to the valve body such that the flow disk is prevented from angular rotation about a center axis of the flow disk; wherein the flow disk has a radially extending key that extends outwardly from a periphery of the flow disk, the radially extending key received by a slot that extends into an interior surface of the valve body causing an interference engagement preventing the angular rotation; and wherein the slot is elongated in the axial direction of the flow disk a distance greater than the axial thickness of the radially extending key to permit axial movement of the flow disk relative to the valve body.
