Rheem-Ruud 60-21621-81 Gas Valve

The Rheem-Ruud 60-21621-81 is a high-capacity, single-stage 24V gas valve engineered for precision fuel regulation in residential and commercial furnaces and boilers. This intermittent pilot ignition valve features a 1/2-inch NPT inlet and a 3/4-inch NPT outlet, delivering a robust capacity of 270,000 BTU/HR at a 1-inch W.C. pressure drop. Factory-calibrated for natural gas with a standard outlet pressure of 3.5 inches WC, it ensures stable burner performance and optimal combustion efficiency. As a genuine OEM Rheem replacement part, this VR8304 series valve serves as a direct drop-in for multiple legacy part numbers, including 60-21215-01 and 60-21621-01. The unit is designed for durability in high-demand HVACR environments, providing technicians with a reliable solution for restoring system safety and consistent heat output. Verify your specific model compatibility to ensure correct port orientation and electrical terminal alignment before installation.

Key Benefits

• High-Flow Capacity: Rated for up to 270,000 BTU/HR, making it suitable for larger furnace and boiler applications.
• Precise Pressure Regulation: Pre-set at 3.5" WC to maintain strict manifold pressure requirements for localized efficiency.
• Broad Compatibility: Replaces a wide range of older Rheem-Ruud gas valve numbers, simplifying truck stock requirements.
• OEM Reliability: Built to original equipment manufacturer specifications to prevent premature solenoid failure and gas leaks.
• Standardized Connections: Features 1/2" x 3/4" NPT fittings for a secure, leak-proof interface with the gas manifold.

Common Questions

Can this natural gas valve be converted to Liquid Propane (LP)?
Yes, this valve can be converted for LP applications using the compatible 60-22513-03 spring kit, though specific orifice changes may be required for the manifold.

What ignition systems is this valve compatible with?
This model is specifically designed for intermittent pilot (IP) ignition systems and should not be used with direct spark or hot surface ignition unless specified by the manufacturer.

Why is the outlet 3/4" while many standard valves are 1/2"?
The larger 3/4" outlet accommodates the higher BTU requirements of heavy-duty furnaces. A reducing bushing (82-21806-62) is often included if a 1/2" connection is required for your specific manifold.
