Siemens Combustion SQM56.680R1Z3 Actuator 319848-301 Enhanced Reliability: The solid-state timingThe Siemens Combustion SQM56. 680R1Z3 Actuator is a high torque, precision engineered industrial motor designed for the rigorous demands of flow control and burner modulation. Operating on a 120V AC power supply, this reversing actuator delivers a robust 350 lb in torque (40 Nm) with a 50 second running time for a full 90 degree rotational travel. Engineered as a motor only assembly (8SwitchNoShaft), it requires a separate AGA58 series drive shaft to
