Weil McLain 511-044-382 Valve

The Weil McLain 511-044-382 is a professional-grade combination gas valve engineered specifically for residential hydronic systems, including CGa Series 2 and CG-7,8 boilers. This 24-volt component features a step-opening delivery system with a 1.2" WC step, ensuring controlled burner ignition and smooth pressure transition during the firing cycle. Designed as an intermittent ignition control valve, it is a direct replacement for natural gas boiler applications requiring a 3/4" x 3/4" NPT threaded connection.

For technicians performing maintenance or emergency repairs, the 511-044-382 gas valve offers high-reliability performance and is cross-compatible with several legacy industry standard parts, including Honeywell VR8304P-4348 and White-Rodgers 36C74-474 modules. This Weil McLain replacement part is essential for restoring precise manifold pressure and safe fuel regulation in spark ignition systems. Its robust construction minimizes mechanical drift, maintaining tight tolerances in high-demand residential heating environments.

• Precise Fuel Regulation: Features a factory-set 1.2" WC step opening to prevent hard ignitions and ensure consistent burner performance.
• High Compatibility: Direct OEM replacement for Weil McLain CG-7 and CG-8 series, as well as EG and PFG boiler models.
• Technical Versatility: Standard 3/4" NPT inlet and outlet sizing allows for straightforward integration into existing gas trains.
• Reliable 24V Logic: Seamlessly interfaces with existing ignition control modules and safety limits for integrated system protection.

Is the 511-044-382 compatible with LP (Propane) gas?
This specific model is calibrated for natural gas. For propane applications, a conversion kit or a specifically rated LP valve must be used to ensure correct manifold pressure.

Can I use this valve to replace a standing pilot system?
No, this is an intermittent ignition valve designed for electronic spark systems. It is not intended for use with standing pilot assemblies.

What are the cross-reference numbers for this valve?
This part is commonly used to replace the Honeywell VR8304P-4348 and White-Rodgers 36C74-474 in Weil McLain residential boilers.
