Abstract
A ball valve and ball valve actuator including a unique valve stem seal and mounting connection between the ball valve and actuator. The stem seal design reduces leakage issues and significantly lengthens the life span of the ball valve and actuator and the mounting connection between the actuator. The ball valve maintains the centrality of the valve stem in connection with the actuator pinion and minimizes torque and shear forces transferred to the valve stem and hence the stem seal itself.
