Abstract
A valve includes a body, a throttling ball, and a shoe. The body includes an upstream flow passage and a downstream flow passage in fluid communication with an interior cavity of the body. The throttling ball is rotatable within the interior cavity on an axis to adjust the valve from a closed position to an open position and includes a fluid conduit extending through the throttling ball, where the fluid conduit is alignable with the upstream flow passage and the downstream flow passage. The shoe is disposed in the cavity abutting an interior surface of the cavity and includes a fluid passage there through having an inlet being alignable with the flow conduit of the throttling ball and an outlet being alignable with the downstream flow passage of the body. The interior surface of the shoe is disposed adjacent to and tracking an external surface of the throttling ball.
