599 Series Zone Valve Actuator SF Series Electronic Valve Actuator 2-position Control Operation Technical Instructions Document No. 155-321P25 January 30, 2008 A 24 Vac, 120 Vac, 208 Vac, or 277 Vac control signal drives the actuator from its normal (0 voltage) position. In the event of power loss, the actuator will return to its normal extended position for the SFA model actuators or normal retracted position for the SFP models.
