McQuay 071278401 GAS VALVE

The McQuay 071278401 GAS VALVE is a high-precision fuel regulation component engineered for specific McQuay and Daikin Applied rooftop units and commercial furnaces. As a redundant gas valve, it features dual solenoid seats to ensure a positive shut-off and meet stringent safety standards for industrial heating applications. Designed for seamless integration with 24V HVAC control circuits, this valve is a direct OEM-spec replacement for the Daikin 071278401, providing the reliability required in high-demand environments where consistent manifold pressure is critical for proper combustion.

This HVAC replacement part is built to handle the rigorous cycling of commercial gas-fired systems. Whether you are performing a seasonal maintenance overhaul or addressing a field failure, the 071278401 offers the standard NPT connections and wiring terminals needed for a straightforward swap in McQuay heating systems. It is essential for technicians to verify the natural gas or LP configuration and adjust the regulator to manufacturer specifications using a calibrated manometer post-installation to ensure peak thermal efficiency and safe burner operation.

• Direct OEM Compatibility: Specifically engineered for McQuay 071278401 and cross-referenced Daikin applications to maintain system integrity.
• Redundant Safety Design: Features dual internal valves to prevent gas leakage and ensure safe ignition sequences.
• Consistent Pressure Regulation: High-quality internal diaphragm maintains stable manifold pressure under varying load conditions.
• Standard 24V Operation: Interfaces perfectly with common commercial HVAC controllers and 24VAC transformers.
• Durable Construction: Built with industrial-grade materials to withstand the high temperatures and vibrations common in rooftop equipment.

• Is this valve compatible with LP (Propane) gas? This depends on the specific orifices and the regulator spring kit installed; always verify the conversion requirements for your specific McQuay model.
• Does this include the pilot gas outlet? Yes, this model typically supports a standard pilot connection for intermittent pilot or standing pilot configurations found in McQuay legacy equipment.
• What is the typical voltage for the solenoids? These are standard 24VAC coils designed to trigger from the primary furnace ignition control board.
