Siemens Combustion SQM50.464R1G3R Reversing Actuator 140 In-lbs, 25Sec, 90° 4-20mA

The Siemens Combustion SQM50.464R1G3R is an electromechanical actuator meant to precisely regulate the flow of gas or air in combustion systems, which include industrial furnaces and HVAC burners. It operates through transforming an electrical signal having a torque of 140 inch-pounds and a reaction time of 25 seconds into a proportional mechanical rotation. By finely controlling the fuel-air conjunction, performance can be enhanced and emissions are minimised while maintaining secure and efficient combustion. To put it a different way, consider the SQM50.464R1G3R as an actuator that reacts to an electrical signal by closing or opening. This makes the ability to precisely control the amount of fuel or air reaches the burner, leading to efficient combustion and less pollution.
