TA-ACTM

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.

Product Information

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.

Key features

Conforms to CE, UL/CSA and RoHS standards

Position indicator

For visibility of stroke position.

Motor jam recovery

System reverses the motor, backs up and again attempts to move to calculated position.

Maintenance free motor

Brushless hysteresis that is capable of continuous stall. For greater control accuracy and dependability.
