Description for Honeywell ML6161C2007

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.


  • 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.
