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. When the actuation sub-assembly is mounted to the valve body, the actuator extends through the planar portion of the valve body wall for engagement with the engagement surface of the valve ball and for engagement with the actuator sub-assembly.
