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
f
t up to 1.05” in diameter by means
of its universal clamp. A crank arm and several mounting brackets are available for
applications where the actuator cannot be direct coupled to the damper shaft
.
