Model

Honeywell ML6161B2024 Non Spring Return Damper Actuator

Product Description

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 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.

FEATURES
 

ï Selectable 45°, 60°, or 90° stroke in both clockwise (cw) or counterclockwise (ccw) directions.

ï 0° to 30° minimum position adjustment (cw or ccw direction) on all models.

ï Magnetic coupling eliminates the need for mechanical stops.

ï Two field-addable auxiliary switches.

ï Auxiliary feedback potentiometer field-addable on select models.

ï Manual declutch on all models.

ï ML7161 and ML7174 models include standard reverse/direct acting rotation switch on outside cover.

ï W7620 Terminal Unit Controller compatibility.

ï Commercial zone damper in W7600 Commercial Zone System compatibility

APPLICATION
 

The 35 and 70 lb-in. (4 Nm and 8 Nm) Non-Spring Return Direct Coupled Actuators (DCA) are control actuators that provide floating or proportioning control for valves and dampers. The proportioning actuators accept a current or voltage signal from a controller to position the damper or valve at any chosen point between fully open and fully closed.
 

Floating actuators are suitable for use with single pole double throw (spdt) floating thermostats or two-position control systems.

Two-position control requires installation of the 201052B Auxiliary Switch.
