or proportional modulation of dampers in HVAC systems. Actuator sizing should be
done in accordance with the damper manufacturer’s specifications.
The actuator is mounted directly to a damper sha
t up to 1.05” in diameter by means
of its universal clamp, ½” self-centered default. A crank arm and several mounting
brackets are available for applications where the actuator cannot be direct coupled to
the dam
