Fail safe modulating actuator for terminal unit valves
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 proportionally, 4-wire, fail-safe on power disruption capability. 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 TA-COMPACT-P, TA-Modulator and TBV-CM.
Conforms to CE, UL/CSA and RoHS standards
