Lennox 85K35 Step-open gas Valve 3/4" 24V 0.9-3.5" WC

The Lennox 85K35 is a step-open gas valve applied to HVAC equipment to manage the amount of gas supplied accurately. Unlike other valves that control the opening size, this valve works with an open and close mechanism. An electrical signal of 24V opens or closes the valve and guarantees a safe and tight shut down of the gas when required. Common in gas furnaces and boilers, the Lennox connects to 3/4 Inch gas lines and operates within a pressure range of 0.9 to 3.5 water column. Through accurate regulation of gases, the Lennox helps to achieve both efficiency and safety in your HVAC equipment.
