Siemens Combustion SQM40.255R11 Actuator 324846-701 use the T1906 or aThe Siemens SQM40. 255R11 is a high torque combustion actuator engineered for precise modulation of fuel and air flow in industrial burner systems. Operating on 110V AC, this modulating motor utilizes a 4 20 mA control signal with a 135 Ohm impedance to drive butterfly valves, dampers, and oil pressure controllers. Designed specifically for counter clockwise (CCW) operation, the unit delivers 90 in lb of torque with a 90 degree stroke time of 25
