Direct coupled damper actuator, non-spring return, 35 lb-in torque, 24 Vac, floating, on/off, SPDT, floating control signal, 90-second nominal driving time, 3/8"-1/2" square or round shaft, 20-125° ambient temperature, 5-95% RH operating humidity range, potentiometer output.
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.
