ABSTRACT:
A trunnion mounted ball valve with cam plates mounted on the stem axis. Cam followers on the seat rings engage in cam slots in the plates to move the seats positively into firm engagement with the ball at the open and closed positions thereof and retract them free of the ball as it is moved between those positions. The seats slide axially in slide rings which are threaded into the body around the flow passage. The valve ball, seat rings, and slide rings may be removed as a unit through the valve top opening.
