As a direct replacement for 93M81, 93M8101, and VR8205S2346, the Lennox 74W26 is a robust, single-stage 24V gas valve engineered for precision in direct ignition systems. This Honeywell VR8215S1230 series valve features 1/2-inch NPT inlet and outlet ports and is factory-calibrated for natural gas at a standard 3.5" W.C. manifold pressure. For technicians handling Lennox HVAC 74W26 installation, the integrated 1/4" hose barb provides a reliable pressure tap for accurate field adjustments between 2.5" and 3.5" W.C. Its dual-solenoid design ensures rapid, safe closure upon loss of power or flame signal, maintaining strict compliance in residential and commercial furnaces. This OEM furnace gas valve is compatible with a wide range of Lennox EL and CG series units, offering a drop-in solution that eliminates the need for manifold modifications in HVAC gas valve replacement projects. Its compact footprint and 1/4" male quick-connect terminals facilitate efficient wiring during time-sensitive service calls. Key Benefits Precise Regulation: Reliable 24VAC solenoid operation ensures consistent natural gas flow for optimal combustion efficiency. Universal Compatibility: Serves as the primary replacement for VR8205S2346 and legacy 93M81 parts across multiple Lennox gas furnace parts categories. Field Adjustable: Features a 3.5" W.C. factory set point with a 2.5" to 3.5" W.C. adjustment range to match specific equipment nameplate requirements. Rugged Build: Designed to withstand temperatures from -40°F to 175°F, ensuring performance in demanding mechanical room environments. Safety Compliant: Dual automatic valves provide a redundant fail-safe mechanism to prevent gas leakage during system interruptions. Common Questions Can the Lennox 74W26 be converted for Liquid Propane (LP) use? Yes, this valve is compatible with LP systems; however, a separate LP conversion kit (typically including a different spring and orifice) is required as it is not included with the standard natural gas unit. Will this valve replace the Honeywell VR8205 series? The 74W26 is the designated technical successor to the VR8205S2346. It maintains the same 1/2" NPT footprint and 24V electrical requirements, making it a direct mechanical fit. What are the signs of a failing 74W26 gas valve? Common indicators include the ignitor glowing without a flame being established, the presence of a "Click-No-Fire" condition where the solenoid engages but gas does not flow, or inconsistent manifold pressure readings that fluctuate outside the 2.5"–3.5" W.C. range.
