Bradford White 239-46990-01 Gas Valve
The Bradford White 239-46990-01 Gas Valve is an OEM replacement Honeywell water heater thermostat specifically engineered for atmospheric vent water heaters. This natural gas water heater valve features a standard 1/2" NPT inlet and is factory-calibrated to a 4" W.C. outlet pressure to ensure precise fuel metering and combustion efficiency. Designed with an integrated thermal switch connection and a built-in piezo igniter assembly, this component facilitates accurate temperature regulation and consistent pilot performance. As a direct-fit replacement for the Bradford White Defender Safety System, it utilizes a sensitive thermopile-powered control circuit to monitor the pilot flame, providing the reliable millivolt operation necessary for off-grid or power-outage functionality. This 1/2" NPT gas control valve replaces older Honeywell and Bradford White 239-series valves, maintaining the integrity of the flammable vapor ignition resistant (FVIR) system while streamlining the installation process for field technicians.
Key Technical Benefits:
- OEM Compatibility: Precision-engineered for Bradford White Defender series atmospheric water heaters.
- Precise Pressure Regulation: Fixed 4" Water Column (WC) output ensures stable burner performance with natural gas.
- Integrated Piezo Igniter: Simplifies the lighting process and reduces the need for external tools during service calls.
- Millivolt Power System: Functions without external electricity by utilizing a thermopile-generated current.
- Robust Safety Controls: Includes a factory-set high-limit energy cut-off (ECO) to prevent overheating.
Common Questions:
How do I troubleshoot a pilot that won't stay lit on this valve?
Verify the thermopile output is at least 650 millivolts and check the thermal switch for continuity. Ensure the pilot orifice is clear and the line pressure matches the 1/2 PSI rating.
Will this valve work on propane (LP) units?
No, this specific 239-46990-01 model is calibrated for natural gas at 4" WC. Using it with propane can lead to overfiring and unsafe equipment operation.
What is the proper shank length for installation?
This valve features a standard shank length compatible with Bradford White glass-lined tanks. Always verify the immersion length against the replaced 239-series gas valve to ensure proper temperature sensing.
