TA-ACT

These control valve actuators use common high strength, glass filled, nylon composite and electric gear motor. Available as normally open or normally closed option, these spring return actuators have 2-position, 2-wire, fail-safe on power disruption capilibity. The actuator is equipped with a dial type position indicator and a M30x1.5 quick disconnect mounting thumbnut to easily connect to our IMI TA balancing and control valves like TBV-C and TA-COMPACT-P.

Product Information

Fail safe high performance on/off actuator for terminal unit valves
