Abstract
A ball type valve in which the ball is rotated by the cooperation of multiple tracks and multiple track followers. Also, a pressure operated permanent lock-out is disclosed. Pressure applied to a piston withdraws an expander from under a lock ring to release a lock-out sleeve. Continued application of pressure drives the sleeve to valve lock-open position where the sleeve is permanently locked to the housing.
