Bradford White 265-40595-02 Gas Valve

The Bradford White 265-40595-02 Gas Valve is an OEM White-Rodgers 37C73U-851 millivolt gas control designed for high-recovery residential water heaters. This 3/4-inch NPT gas valve features a consolidated manifold design with an integrated high-limit energy cut-off (ECO) and a built-in pressure regulator factory-set for natural gas. Engineered for precise thermopile-driven gas regulation, it eliminates the need for external power sources, making it a critical component for atmospheric vent water heater repair. The 1-1/2 inch shank depth and 3/4-inch NPT inlet/outlet offer a direct-fit solution for commercial-grade Bradford White tanks. When troubleshooting water heater pilot outages or erratic burner cycles, this valve provides the necessary millivolt safety circuit integrity. As a veteran-preferred HVAC replacement part, this Robertshaw style water heater control ensures accurate temperature sensing through its liquid-filled copper bulb, maintaining consistent BTU output and thermal safety compliance for professional contractors and facility managers.

• OEM Precision: Genuine Bradford White replacement part ensures exact fitment and manifold alignment without field modifications.
• Integrated Safety: Features a mechanical energy cut-off (ECO) to prevent tank overheating during sensor failure.
• Reliability: Heavy-duty cast aluminum body and internal stainless steel components resist corrosion in high-humidity mechanical rooms.
• Simplified Installation: Standard 3/4-inch inlet and outlet piping connections minimize labor time for hot water heater gas valve swaps.

Common Technical Questions

What are the symptoms of a failing 37C73U-851 gas valve?
Common indicators include the pilot light failing to stay lit despite a strong thermopile millivolt signal, or the main burner failing to ignite when the thermostat dial is turned to the 'On' position.

Can this gas valve be converted to Liquid Propane (LP)?
No. The 265-40595-02 is calibrated specifically for Natural Gas. Using an incorrect fuel source can cause hazardous combustion conditions; always verify the manifold pressure requirements on the unit nameplate.

How do I test the millivolt circuit on this Bradford White control?
Using a multimeter set to DC millivolts, check the thermopile output at the valve terminals. A healthy system should read between 650mV and 850mV under no-load conditions to ensure the electromagnetic safety valve stays energized.
