R-410A Compatibility: Specifically designed for the pressure ranges and performance characteristics of R-410A systems

Using this valve with R-410A will lead to improper metering and potential system failure due to different pressure-temperature characteristics

this unit provides superior resistance to formicary corrosion compared to traditional copper coils

Inspect for "glazing" on the sidewalls

Siemens Combustion SQM50.464R1G3 Actuator 318518-761 this is the electrical harnessThe Siemens SQM50. 464R1G3 Actuator is a high precision reversing motor designed for the precise positioning of dampers and flow control valves in industrial combustion systems. Engineered for demanding environments, this direct coupled actuator delivers 140 lb in torque with a fixed 25 second run time for 90 degree standard rotation. This specific model operates on 110 120V and uses a 4 20mA modulating signal for seamless integration with burner
