A.o. Smith 100093794 Natural Gas Control Valve

Product Description

The A.O. SMITH 100093794 is a natural gas control valve designed for use in water heating systems. This valve regulates gas flow to the burner assembly, controlling ignition and maintaining safe operating conditions throughout the heating cycle. Licensed plumbers and HVAC technicians typically service this component as part of routine water heater maintenance or when diagnosing burner performance issues. The valve is a direct OEM-style replacement intended to restore proper gas regulation in systems where the original valve has failed or become unreliable.

This control valve is suited for residential and light-commercial water heater applications running on natural gas. It is installed inline with the gas supply line feeding the burner, where it manages both thermostat-controlled gas flow and safety shutoff functions. Service professionals will encounter this valve during water heater diagnostics when symptoms include failure to ignite, inconsistent water temperature, or pilot outage.
