A ball valve having an anti-rotational pressure plate (20) that allows for a balanced pressure load on a valve member (14) is provided. Additionally, the pressure plate (20) can also fix the rotation of an adjacent flow disk (18), allowing for angular-orientation specific flow characterizing features to be used with the flow disk (18). By fixing the rotation of the flow disk (18), the ball valve can characterize flows using a greater variety of flow disk (18) geometries, including angular-orientation dependent and angular-orientation independent flow disks. Further, the pressure plate (20) could also be directly in the form of a flow disk (18) that has anti-rotation features. |
