Weil McLain 511-044-360 Gas Valve

The Weil McLain 511-044-360 Gas Valve is an OEM combination gas control engineered specifically for residential hydronic systems. This 24V gas valve features standard 1/2" NPT inlet and outlet connections, housing a dual automatic seat design to meet safety codes for shutoff reliability. As a high-performance boiler replacement part, it is the primary control for the burner manifold on Weil McLain CGa, CG, and EG series cast iron boilers, specifically optimized for natural gas standing pilot applications. The internal servo-pressure regulator is factory-set to maintain 3.5" W.C., ensuring stable combustion across the full input range of the appliance. For technicians performing a gas valve troubleshoot, this unit provides a direct-fit solution that eliminates compatibility issues with existing 24-volt ignition control circuits. Its rugged construction supports the demanding cycle rates typical in high-efficiency heating environments without sacrificing safety or performance.

• OEM Precision: Guaranteed compatibility with Weil McLain CG, EG, and CGa boiler models prevents installation delays.
• Standardized Fit: 1/2" x 1/2" NPT threaded connections allow for a straightforward swap with existing gas train piping.
• Enhanced Safety: Built-in dual main configuration provides redundant gas shutoff in the event of power loss or pilot failure.
• Optimized Pressure: Integral natural gas regulator maintains consistent pressure for efficient burner operation.

• Is this valve compatible with LP (Propane) systems? No, the 511-044-360 is factory-configured for natural gas. Always verify the fuel type on the boiler rating plate before installing.
• Does this include a new thermocouple? This is the combination gas valve only; standing pilot components like thermocouples are sold separately.
• Can I use this on other boiler brands? While the threading is standard, this part is specifically calibrated for the input requirements of Weil McLain boilers.
