Description
The Lennox 18M65 2-Stage Natural Gas Valve is a gas control component that is used in HVAC systems, especially in Lennox furnaces and is high efficiency. This 2-stage gas valve is sized at 1/2” and has a 1/2”-1/4” NPT pipe threading for the supply of natural gas for the better fuel control. These valves afford the furnace considerable control and flexibility because they provide two-step control over the much-needed gas flow and regulate heat output depending on the conditions or the season. This two-tier control minimizes cycling, saves fuel, and keeps the room temperatures constant.
