Direct Coupled Damper Actuators—Non-Spring Return

ML6161A,B ML6161C,D ML7161

ML6161; ML7161 Non-Spring Return Direct Coupled Damper Actuators, 35 lb-in

Used to control dampers in HVAC applications and for mounting on ball valves; suitable for use with modulating (2-10 Vdc) thermostats or building automation controls.

• Control for air damper applications with up to 10 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
