Mcquay Daikin 073336504 Valve

The McQuay Daikin 073336504 is a heavy-duty single-stage gas valve engineered for precision fuel regulation in commercial and industrial HVACR systems. Operating on a 120V pilot duty circuit, this component is factory-calibrated for Natural Gas with a standard 3.5" W.C. outlet pressure setting. Featuring 3/4" NPT inlet and outlet ports, it ensures high-flow capacity and consistent manifold pressure for reliable burner ignition and flame stability. This OEM replacement gas valve is designed to meet the strict tolerances required by Daikin Applied air handling units and rooftop systems, ensuring seamless integration with existing furnace controls. Use this valve to resolve issues with erratic gas flow, failed solenoid coils, or inconsistent pilot operation. For technicians servicing Daikin equipment, maintaining combustion safety and thermal efficiency depends on utilizing exact-match components like the 073336504 to prevent pressure drops and ensure proper BTU input throughout the heating cycle.

• Direct OEM Compatibility: Specifically designed for McQuay and Daikin Applied equipment to eliminate field-fitment HVAC part installation issues.
• Precise Pressure Regulation: Fixed 3.5" W.C. setting provides stable manifold pressure for optimal combustion efficiency.
• Industrial Build Quality: Robust solenoid construction handles high-cycle demand in commercial gas heating applications.
• Standardized Porting: 3/4" NPT connections allow for straightforward integration into existing gas trains without custom piping.
• Reliable 120V Control: Optimized for standard control voltage circuits found in high-capacity furnaces and makeup air units.

Can this valve be field-converted for Liquid Propane (LP)?
This specific model is calibrated for Natural Gas at 3.5" W.C. Field conversion is not recommended without a certified manufacturer conversion kit; verify the orifice and spring requirements for your specific BTU load.

What are the symptoms of a failing McQuay 073336504 valve?
Common indicators include failure to open despite receiving 120V at the coil, fluctuating manifold pressure during a call for heat, or an "internal leak" where gas passes through the valve when it should be closed.

How do I verify compatibility with my Daikin unit?
Always cross-reference the Daikin part number 073336504 against the data plate on your air handler or furnace. This valve is frequently found in high-efficiency commercial rooftop units requiring 3/4" gas valve capacity.
