ABSTRACT:
A fluid flow control valve utilizes a ball which is rotated about an axis greater than 0 degrees and less than 90 degrees to the direction of fluid flow. The ball member utilizes a fluid flow conduit through its center with a flat surface disposed at an angle to the fluid flow conduit. When in the closed position, the flat surface is disposed flush with a valve face on one port of the valve. The ball is also disposed so that its center is less than a radius length from the surface defined by the valve face.
