It is an additional object of the present invention to provide a valve operator mechanism for a plug type valve, the mechanism comprising a cam sleeve assembly having a pin that interconnects the trunnion and the cam sleeve and that rides in a pair of L-shaped grooves to provide the requisite direction of motion control to effect opening and closing the valve, the operator also having a pair of variable angle slots in the cam sleeve for varying the instantaneous seating, unseating and rotational forces applied to the trunnion during the opening and closing of the valve.
