Weil McLain 511-044-256 Gas Valve

The Weil-McLain 511-044-256 is a high-performance combination gas valve designed specifically for the Weil-McLain CGa and EG series boilers, including models CGa-7, CGa-8, EG-7, and EG-8. Built for reliability in demanding HVACR environments, this 24V gas control features a step opening (1.2" step) design that ensures smooth burner ignition and controlled gas flow. Professionals should note that the 511-044-256 serves as the direct OEM replacement for 1149171 and is often cross-referenced with the Honeywell VR8300C4050. With a 3/4 inch NPT inlet and outlet, this valve is engineered for natural gas standing pilot systems, providing precise regulation for industrial and commercial heating applications. Utilizing durable, corrosion-resistant internal components, this valve maintains consistent performance across varying operational pressures, making it the standard choice for technicians performing critical boiler repairs.

Common Questions

What boiler models is this gas valve compatible with?
This 3/4 inch gas valve is primarily utilized in Weil-McLain CGa-7, CGa-8, EG-7, and EG-8 boilers. Always verify the specific MPN and boiler series before installation.

Can this replace a Honeywell VR8300C series valve?
Yes, the 511-044-256 is the direct Weil-McLain equivalent to the Honeywell VR8300C4050. It maintains the same 1.2" step opening and electrical requirements.

Is this valve rated for LP/Propane conversion?
This specific model is calibrated for natural gas systems. If your application requires Propane (LP), you must use the appropriate manufacturer-specified conversion kit or the dedicated LP valve model.
