The M9108-xGx-2 Series direct-mount electric
actuators operate on 24 VAC power and are available
for use with on/off, floating, or proportional controllers.
These non-spring return actuators are easily installed
on a Variable Air Volume (VAV) box, a damper with a
round shaft up to 1/2 inch (13 mm) in diameter, or a
square shaft up to 3/8 inch (10 mm).
The M9108 models have 70 lb·in (6 N·m) running
torque. They have a nominal 60-second travel time for
90° of rotation at 60 Hz (72 seconds at 50 Hz) with a
load-independent rotation time.
