Sterling 11J28R04980-003 Gas Valve Freon High-Temperature Calibration: Factory-set to 300

High-Temperature Calibration: Factory-set to 300 degrees Fahrenheit to provide accurate thermal protection for the burner compartment

As a direct substitute for the 36453B001 flame sensor

which is critical for maintaining long-term system stability

Repeated tripping is usually indicative of low airflow

Critical Redundancy: Vital for Ultra Gas 550/750 boilers which utilize dual-sensor configurations for balanced thermal monitoring

Sterling 11J28R04980-003 Gas Valve Freon High-Temperature Calibration: Factory-set to 300The Sterling 11J28R04980 003 Gas Valve is a direct replacement, intermittent pilot control unit designed for high efficiency gas fired heating systems. This 3 4 inch gas valve is technically identical to the Honeywell SV9640M4124 SmartValve system, integrating both the pilot control and the main gas flow regulation into a single robust component. Operating on a 24V AC ignition system, it provides precise electronic ignition control and features a 1 2"
