Abstract
The isolation valve assembly includes a ball member stabilized relative to a ceramic ring, an upper ball housing and a lower ball seat with a set of shifting bars, a set of locking bars, and a set of supporting bars. The shifting bars rotate the ball member between opened and closed configurations, while the locking bars and supporting bars stabilize the ball member. The supporting bars are off set from the shifting bars and locking bars, and the supporting bars are anchored to the assembly separate from the locking bars and shifting bars. The actuation of the shifting bars is independent from the locking bars and the supporting bars so that the ball member can be held in the opened or closed configuration with more stability.
