2-10 Vdc Actuator-300 lb-in, Non-Spr Ret
Overview
Honeywell ML7294 non-spring return direct coupled actuators provide proportioning control of dampers or valves in HVAC applications. It uses a current or voltage signal from an electronic controller to position a damper or valve at any point between fully open/closed.
Features
- Mount on 1/2- to 3/4-in. round or square shafts; moutn on 1-in. round shafst with appropriate 1-in. insert
- 300 lb-in. (34Nm) torque
- Magnetic coupling eliminates mechanical stops or limit switch adjustments by limiting stall torque; nominal stall torque at room temperature of 68F (20C) is 410 lb-in.
- Ninety-five degree stroke compresses rubber/neoprene gaskets on 90 low leakage dampers
- Declutch features allows manual adjustment
- 165-second synchronous timing eliminates need for feedback position indication in closed-loop temperature control applications
- Standard reverse/direct acting rotation switch on outside cover
- Both single-point and three-point mounting capatibility
- Models available with 2-10 Vdc and 4-20 mA inputs; models available with 2-10 Vdc feedback signal
