Title: BALL VALVE SYSTEM AND METHOD
Abstract:
A system configured to adjust a seat (38,40) of a ball valve (10) includes a cam-actuated valve that is configured to be controlled via rotation of a stem (20) coupled to a ball (16) of the ball valve. The cam-actuated valve is configured to enable a flow of fluid at a first pressure to an opening extending through a body (12) of the ball valve (10) to drive the seat (38,40) of the ball valve (10) away from the ball (16) when the cam-actuated valve is in a first position.
