Abstract: A valve assembly includes a valve body, with an inlet, an outlet, and a chamber extending between the inlet and the outlet, an actuator, and an actuation sub-assembly. Positioned in the chamber is a valve ball with a ball body and a transverse passage extending through the ball body. The valve ball is positionable between a valve open position wherein said transverse passage provides fluid communication between the inlet and the outlet and a valve closed position wherein the ball body blocks the fluid communication between the inlet and the outlet. The actuation sub-assembly engages the actuator, which in turn engages the valve ball. In addition, the valve body includes a valve body wall with a planar portion. The planar portion includes a mounting surface for mounting the actuation sub-assembly to the valve body.
