Honeywell ML616B2024 Floating, SPDT Actuator with 35 lb-in, Non-Spring Return, 24 Vac +/-20%, 50Hz, 60Hz. 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
The ML6161B2024 acts as a control for air damper applications with up to 10 sq.ft. assuming 3.5 in-lb per sq.ft. of damper area, velocity independent. Contains a superior A/C synchronous submotor for consistent timing and actuator longevity. Eliminates need for limit switches or mechanical stops by providing magnetic coupling and 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.
