Rheem-Ruud SP5870E Gas Valve

The Rheem-Ruud SP5870E is a high-performance Natural Gas Millivolt Gas Valve engineered for heavy-duty residential and commercial applications. Built by Robertshaw (Unitrol 7000MV series), this valve features 1/2" NPT inlet and 3/4" NPT outlet configurations, making it a critical OEM replacement part for specific Rheem and Ruud water heaters and gas-fired appliances. This standing pilot control utilizes a thermopile-driven millivolt system, allowing for safe gas flow regulation in off-grid or power-sensitive installations without the need for external line voltage. The integrated pressure regulator is factory-set for Natural Gas (NG) to maintain a consistent manifold pressure of 3.5" W.C., ensuring optimized combustion and reliable ignition. Designed for versatility and easy installation, this combination gas control combines a manual main switch, safety pilot, and millivolt actuator into a single compact housing, providing seasoned contractors with a precise solution for restoring system integrity and performance.

• Robertshaw Unitrol 7000MV Series: Reliable millivolt operation with a standard pilot configuration.

• Natural Gas Optimization: Factory-calibrated for NG with a dedicated integrated pressure regulator.
• Millivolt Control System: Operates using thermopile output, eliminating the need for 120V power.
• Safety-First Design: Includes a manual shut-off, pilot adjustment, and safety thermocouple/thermopile connection.

Can I use this valve for an LP (Propane) conversion?
Standard SP5870E units are factory-set for Natural Gas. While the Robertshaw 7000 series often supports conversion, a specific LP conversion kit must be used to ensure safe manifold pressure for propane applications.

Why is the pilot not staying lit after a valve replacement?
Ensure the thermopile is generating at least 750mV and that the pilot flame is properly engulfing the element. Check all wiring terminals for a clean, tight connection to the millivolt gas valve.

Is this a universal replacement for all Rheem water heaters?
No, this is a model-specific OEM part. Always verify the shank length and thread size (1/2" x 3/4") and confirm the BTU capacity against your appliance nameplate before installation.
