Abstract
The ball valve assembly includes a valve body , a ball , a seat ring , a support ring , and an actuator sleeve surrounding the ball and axially moveable within the valve body for rotating the ball between the open position and the closed position. A plurality of seals seal with the seat ring, the actuator sleeve, the support ring, and the valve body. The actuator sleeve maintains fluid pressure within the valve body. The ball, support ring and seat ring are each formed from a selective material to enhance life of the ball valve assembly. A pair of pins each extend in a slot within the ball and holes in the sleeve, and preferably the pair of pins and the ball rotate with respect to the sleeve as the sleeve moves axially within the valve body.
