35/70 lb-in Non-Spring Return Direct Coupled Actuator

ML6161, ML7161, ML6174, and ML7174 35 and 70 lb-in non-spring return direct coupled actuators (DCA) are control actuators that provide floating or proportioning control for valves and dampers.

ML6161, ML7161, ML6174, and ML7174 35 and 70 lb-in 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 2-position control systems. The 2-position control requires installation of the 201052B auxiliary switch.

Features & Benefits:
  • Selectable 45, 60, or 90° stroke in both clockwise (CW) or counterclockwise (CCW) directions
  • 0 to 30° minimum position adjustment (CW or CCW direction) on all models
  • Magnetic coupling eliminates the need for mechanical stops
  • Two field-addable auxiliary switches
  • Auxiliary feedback potentiometer field-addable on select models
  • Manual declutch on all models
  • ML7161 and ML7174 models include standard reverse/direct acting rotation switch on outside cover
  • W7620 terminal unit controller compatibility
  • Commercial zone damper in W7600 Commercial Zone System compatibility
Certifications:
  • UL: File No. E4436; Guide No. XAPX2
  • UL94-5V: Meets Plenum Requirements
  • CSA (includes Auxiliary Switch)
  • CE: ML7161E, ML7174E Only
