1. A well system comprising:
a wellhead positionable at a surface of a wellbore;
a ball valve for coupling to the wellhead, the ball valve being movable between an open position and a closed position;
a hollow core electric motor positionable adjacent to the ball valve to move the ball valve between the open position and the closed position;
a power source operable to provide electric power to the hollow core electric motor;
a hydraulic pump to interact with the hollow core electric motor to energize hydraulic fluid of the hydraulic pump; and
a hydraulic rotary actuator positionable to interact with the hydraulic fluid of the hydraulic pump to move the ball valve between the open position and the closed position.
