ABSTRACT:
A valve actuating mechanism for valves particularly of the plug valve type wherein a plug member is movable between operative positions by both linear and rotary movement. The valve actuating mechanism incorporates means for imparting linear movement to a valve stem and separate means for accomplishing 90.degree. rotary movement to the valve stem during such linear movement. Rotary movement of the valve stem is accomplished by pivotal linkage means that is interconnected both with the valve stem and valve body structure by means of omni-directional pivots.
