Abstract
Ball valves, methods to close a ball valve, and methods to form a well barrier are discussed. A ball valve includes a valve housing and a ball that is rotatably movable from an open position to a closed position. The ball valve also includes an actuation mechanism operable to rotate the ball from the open position to the closed position, where a fluid passage of the ball is not aligned with a fluid passage of the valve housing while the ball is in the closed position. The ball valve further includes a sleeve disposed in the valve housing and operable to shift from a first position to a second position to actuate the actuation mechanism.
