Description
The Siemens Combustion SQM56.664R1G3 Reversing Actuator is a control component that adjusts the valve position by transforming electrical signals into accurate mechanical motion in HVAC systems in combustion, and burner applications. It uses a 420 mA control signal at 120 V and is rated at 400 PSI with a 50-second stroke time to adjust the flow of fuel, or air via valves connected to it. It is located in the control linkage and assists in providing the correct modulation, stable combustion conditions, and control the operations of the system.
