Description
Direct coupled actuator, non-spring return, 35 lb-in torque, 24 Vac, floating control signal, SPDT, 90-second nominal driving time, 3/8″-1/2″ square or round shaft, 20-125°F ambient temperature, 5-95% RH operating humidity range.
ML7161/ML7174 Non-Spring Return Direct Coupled Actuators (DCA) 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.
Features & Benefits:
- Selectable 45°, 60°, or 90° stroke in both clockwise (CW) or counter clockwise (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
- Standard reverse/direct acting rotation switch on outside cover
- Superior A/C synchronous sub motor for consistent timing and long life
