Honeywell MS4103 manual Non-Spring Return Direct Coupled Actuator, ML6161 ML7161

Non-Spring Return Direct Coupled Actuator

ML6161; ML7161

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 to 10 sq.ft. assuming 3.5 lb-in. per sq.ft. of damper area, velocity independent.

•Superior A/C synchronous sub-motor 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 in. or 1/2 in. square or round damper shaft.

•Selectable 45, 60, and 90 degree stroke in either clockwise or counterclockwise direction.
