Abstract:
A valve assembly is provided. The valve assembly includes a valve body having a valve chamber and a plurality of ports into the valve chamber. The plurality of ports include a first port, a second port, and a third port. The first port and the second port are aligned with a common axis and located on opposite sides of the valve chamber. The system further includes a valve member located within the valve chamber. The valve member is a rotatable ball having a fluid passage that extends through the ball and includes an opening at the end of the ball. The fluid passage is substantially oval-shaped when viewed at the opening in a direction parallel to the fluid passage. The valve assembly further includes a valve stem that is coupled to a valve member and has a first end that extends from the valve body.
