This high-performance gas control valve is designed for modern heating systems utilizing an intermittent pilot ignition. Featuring a 1/2-inch inlet and a 3/4-inch outlet, this component ensures precise fuel regulation for residential and light commercial furnaces and boilers. The 'proven pilot' technology provides an essential safety layer by confirming the pilot flame is established before releasing gas to the main burner, preventing unburned gas buildup. Engineered with a slow-opening mechanism, it facilitates a smoother, quieter startup, reducing mechanical stress on the system and minimizing ignition noise. This reliable replacement part is ideal for restoring the efficiency and safety of high-efficiency HVAC equipment.
