Hand wheel Operation
A hand wheel Operation is provided to allow manual operation of the valve during electrical power interruption. During electric operation of the actuator, the hand wheel is mechanically disengaged from the drive. To engage hand wheel operation, the hand/auto selection lever is pushed down and released after which hand wheel operation remains selected. When electrical operations takes place the actuator will automatically return to motor drive without lever or hand wheel kickback
