Raypak 004879F Gas Valve

The Raypak 004879F Gas Valve is a critical combustion component designed for precise fuel regulation in high-efficiency pool and spa heaters. Operating on a 24V AC intermittent ignition system, this valve is factory-set for 4" WC natural gas but can be field-converted with the appropriate regulator spring kit. Utilizing 3/4" NPT inlet and outlet ports, it provides high-capacity flow rates necessary for large BTU inputs without excessive pressure drops. As the direct engineering successor to the 012659F replacement valve, the 004879F features a dual-solenoid safety design, ensuring immediate shut-off if the flame signal is lost or the limit string opens. This Honeywell or Robertshaw equivalent integration emphasizes reliability in harsh mechanical room environments, maintaining consistent manifold pressure for optimal thermal efficiency and reduced NOx emissions.

• Direct OEM Fit: Ensures seamless mechanical alignment with Raypak 004879F atmospheric heaters, reducing labor time during field swaps.
• High-Flow Capacity: The 3/4" gas valve ports handle high-demand cycles without causing nuisance pilot outages or flame lifting.
• Verified Compatibility: Replaces legacy part number 012659F, maintaining the exact electrical footprint and mounting profile for older Gemini or 36C series setups.
• Corrosion Resistance: Engineered to withstand the humidity and chemical exposure common in indoor and outdoor pool heater enclosures.

Is the Raypak 004879F compatible with Propane (LP) units?
The 004879F is configured for natural gas at 4.0" WC. For Raypak LP gas valve conversion, a specific manufacturer-approved spring kit must be installed to handle the higher manifold pressure requirements of propane.

What are the electrical requirements for this solenoid valve?
This is a 24V gas valve designed to work with standard spark-to-pilot or hot surface ignition control modules. Ensure the transformer has sufficient VA capacity to pull in both solenoid coils simultaneously.

Can I use this to replace a 1/2" NPT gas valve?
This valve uses 3/4" NPT threading. While bushings can be used, we recommend maintaining the original pipe diameter to ensure the BTU rating of the heater is not compromised by gas starvation.
