Application
This combination gas control valve is a genuine Weil McLain OEM replacement part, engineered for use on Weil McLain boilers requiring two-stage gas control. The integrated low fire and high fire operators allow the burner to stage its output, improving combustion efficiency, reducing thermal shock to the heat exchanger, and lowering operating costs. The built-in main pressure regulator ensures stable gas pressure delivery to the burner regardless of supply pressure fluctuations, while the 1/8″ NPT downstream pressure tapping allows technicians to quickly verify operating pressure during startup and routine maintenance.
