Rheem-Ruud SP14270F Control Valve

The Rheem-Ruud SP14270F Control Valve is a critical OEM replacement gas valve designed for specific atmospheric water heater applications. This combination natural gas control features a built-in adjustable thermostat and a high-limit energy cutoff (ECO) for precise temperature regulation and safety. Engineered for compatibility with Rheem, Ruud, and Richmond water heaters, the SP14270F manages gas flow to both the pilot and main burner assemblies. As a White-Rodgers 37C73U-172 equivalent, it utilizes standard 1/2-inch NPT inlet and outlet connections and a thermopile-driven millivolt system, eliminating the need for external power. Field technicians must verify the manifold pressure and shank length to ensure a proper fit within the combustion chamber. This natural gas water heater valve is calibrated for standard residential BTU inputs, providing reliable ignition and consistent thermal performance in high-demand environments.

• Direct OEM replacement ensures specific housing and mounting alignment for Rheem-produced tanks.
• Integrated millivolt thermostat allows for standalone operation without electrical wiring.
• Robust internal regulator maintains stable manifold pressure for efficient combustion.
• Standard 1/2" NPT threading facilitates straightforward mechanical installation for service contractors.
• Includes a safety High-Limit ECO to prevent tank overheating and potential pressure relief activation.

Is the SP14270F compatible with LP (Liquid Propane) units?
No, this specific model is orifice-drilled and regulated strictly for natural gas applications. Converting this valve for propane use is not recommended due to fixed pressure settings.

Does this valve include the thermal well?
Yes, the SP14270F features an integral shank designed to thread directly into the water heater tank to monitor internal temperatures.

What causes a gas control valve to fail to stay lit?
Failure is often attributed to a degraded thermopile or a tripped ECO. If the pilot lights but the main burner fails to kick in, the internal electromagnet in the valve may be faulty.
