Lennox 83W12 2-Stage Gas Valve 24V 3.5 Inch Water Column 1/2 Inch

The Lennox 83W12 is a 2-stage gas valve designed for optimal performance in natural gas-fired, two-stage heating systems. It precisely controls the flow of gas in two stages, allowing your furnace to operate efficiently at both high and low heating demands. This translates to dependable comfort and optimized fuel usage. Made of aluminum for durability, the valve features a 1/2 inch inlet and a maximum regulatory capacity of 150,000 Btu. It operates on a standard 24-volt electrical system and uses a threaded NPT connection for easy installation into compatible HVAC equipment. In two-stage heating systems, the 83W12 initially opens to a low stage, providing gentle heating for milder conditions. When additional warmth is needed, the valve transitions to a higher stage, delivering a greater gas flow to meet your heating demands. This two-stage operation helps to avoid excessive on/off cycling, resulting in smoother temperature control and improved efficiency. Overall, the Lennox 83W12 gas valve is a key component for reliable and efficient heating performance in your two-stage, natural gas furnace.
