AMI 120 NL-1
The AMI 120 NL-1 is a 2 point (ON/ OFF), 3 wire actuator used with the AB-QM pressure independent control valves installed on hot or chilled water system applications. This actuator is installed on AB-QM valve sizes ranging from 1/2” to 1- 1/4”. The AB-QM assembly is suitable for installation within fan coil units, VAV, induction units or additional units that require combined balancing and valve control, which could be located within enclosures or plenum rated spaces.
As a 3 wire actuator, it receives constant power to travel to its default position and upon receipt of input signal will travel in the opposite direction. Designed within the actuator is an overload and gap function to prevent unnecessary travel from the actuator.
