Rheem-Ruud SP20164 Gas Valve

The Rheem-Ruud SP20164 Gas Valve is a critical OEM replacement part designed for precision fuel regulation in residential and commercial natural gas water heaters. This 1/2" NPT gas control valve (thermostat) operates with a 4" WC (Water Column) manifold setting, ensuring stable burner performance and accurate temperature management. Engineered for standing pilot models, this direct-fit component is compatible with Rheem, Ruud, and Richmond atmospheric units, including specific models like the PROG40S-40N RH62. The robust brass and steel construction provides high thermal resistance and dependable gas flow modulation. As a combination gas control, it integrates the safety shut-off and thermostatic regulation into a single housing, simplifying field installation for contractors. This technical HVACR component utilizes a standard 1/2-inch inlet and outlet connection, making it a reliable choice for restoring system efficiency and safety benchmarks after a primary valve failure.

• Precise Gas Regulation: Factory-calibrated for 4" WC manifold pressure to maintain optimal combustion efficiency in natural gas applications.
• OEM Compatibility: Serving as a genuine Rheem replacement part, it ensures seamless integration and removes the troubleshooting variables associated with universal valves.
• Integrated Safety: Features a built-in safety shut-off mechanism that halts fuel flow if the pilot flame is lost.
• Universal 1/2" Connections: Standard 1/2-inch NPT inlet and outlet sizing allows for straightforward swap-outs on legacy standing pilot tanks.
• Broad Fitment: Compatible with most Rheem-Ruud standing pilot heaters, excluding power vent and direct vent configurations.

• Is the SP20164 compatible with LP (Propane) units? No, this specific model is orifice-drilled and spring-loaded specifically for natural gas (NG). Using this on propane units creates a hazardous over-firing condition.
• Can this replace a power vent gas valve? No. This valve is strictly for standing pilot atmospheric models and does not have the electrical interfaces required for power-vented or direct-vented systems.
• Does the kit include mounting accessories? This unit is typically supplied as the gas control thermostat itself; always verify if additional adapter nuts are required for specific tank geometries.
