Powermite SQS65 and SQS65.5 Electronic Valve Actuators require a 24 Vac supply and receive a 0 to 10 Vdc or a 0 to 1000 Ohm control signal to proportionally control a valve. SQS85.53 electronic valve actuators require a 24 Vac supply and receive a floating control signal to provide floating control. Actuators work with Powermite MT Series Valves with a 7/32-inch (5.5 mm) stroke.


The SQS Electronic Valve Actuators are for use in small to medium HVAC installations with Powermite MT Series valves that have a 7/32-inch (5.5 mm) stroke.
