Description
The Honeywell ML6174B2019 is a robust direct-coupled damper actuator designed for HVAC systems requiring precise, non‑spring-return control. With 70 lb‑in of torque and a smooth 90‑second transit, it’s perfect for modulating airflow in VAV terminal units, zone dampers, or ball valve applications.
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.
