Used to control dampers in applications such as variable air volume (VAV) terminal units and for mounting on ball valves; suitable for use with SPDT or floating thermostats or building automation controls.
Features
Control for air damper applications with up to10 sq.ft. assuming 3.5 in-lb per sq.ft. of damper area, velocity independent.
Superior A/C synchronous submotor for consistent timing and actuator longevity.
Eliminate need for limit switches or mechanical stops by providing magnetic coupling.
All models include manual declutch lever, and bag assembly with two minimum position setscrews.
Mount directly on 3/8 inch or 1/2 inch square or round damper shaft.
Selectable 45, 60, and 90 stroke in either clockwise or counterclockwise direction.

This was purchased as an exact replacement for a ten year old HRV unit fresh air damper control. The new model has the same specifications and dimensions, so it worked exactly as expected. A good thing about this model is the magentic drive, which allows the damper to fully open and close without using limit switches at each end of travel; the motor just keeps running when the torque limit is reached. Alternatively, power can be disconnected after the appropriate time is allowed for damper positioning, as the present position will remain until power is re-applied.

Supply house is awesome but...
Wish these actuators would stop failing. I have 3 of them in my house and have replaced them at least 1 time in the 3 years I've had my zoning system. I've learned to keep a spare one on hand for when the next one fails.
Easy to replace but wish they lasted longer.

I would purchase this again.
This damper was easy to replace, have to take a little time to read the instructions in the box, but I would definitely purchase again.
