Raypak 004094F Gas Valve

For high-demand commercial boilers and large-scale hydronic systems, the Raypak 004094F 24V 1 1/4" Gas Valve is an essential OEM component designed for high-capacity natural gas regulation. As a veteran-grade replacement part, this 24VAC gas valve features a 1-1/4" NPT connection, engineered specifically for Raypak heater repair and maintenance on heavy-duty units like the Raytherm V-88, 500, and 1000 series. This combination gas valve integrates an automatic safety shutoff and precise manifold pressure regulation to ensure consistent BTU output and prevent dangerous gas accumulation during flame-out scenarios. When troubleshooting pool heater ignition failure or erratic burner behavior, replacing a sticking or non-responsive solenoid is critical for operational safety. This genuine Raypak part maintains the factory-specified flow rates necessary for commercial-grade combustion air-gas ratios, ensuring your system remains up to code and fully functional during the peak heating season.

• 1-1/4" NPT high-flow capacity designed for large commercial Raypak heating units.
• Operates on a standard 24V heater control circuit for seamless integration with existing ignition boards.
• Equipped with an integrated safety shutoff to mitigate the risk of unburned gas buildup.
• Provides precise gas pressure regulation, maintaining steady burner performance and efficiency.
• Heavy-duty OEM build quality ensures long-term reliability in demanding hydronic environments.

Is this gas valve compatible with propane (LPG) units?
This specific model is calibrated for natural gas (NG) applications. Using it with propane requires a separate conversion kit or a dedicated LP valve to ensure safe combustion pressures.

What are the signs that my current 1-1/4" gas valve is failing?
Common indicators include the heater failing to ignite despite a consistent spark, the smell of gas near the heater during the off-cycle, or the internal solenoid clicking without actual gas flow to the burner tray.

Can I use this for residential Raypak 206A-406A heaters?
Typically, residential models use smaller 1/2" or 3/4" valves. This 1-1/4" valve is built for much larger, high-BTU commercial systems; always verify your heater’s port size and manifold requirements before installation.
