Southbend 4440410 NAT/LP Gas Burner Valve 1/8" MPT X 1/8" MPT 0.240" Stem 90°

The Southbend 4440410 Gas Burner Valve regulates fuel transfer into the combustion chamber section through a manually controlled passage. Rotation of the internal stem shifts the closure and changes the opening for flow through the valve structure. NAT/LP specifies natural gas and liquid propane service, while both connections have 1/8-inch MPT threads, the stem measures 0.240 inch, and adjustment follows a 90-degree rotation. Installed between the supply route and burner inlet, the assembly alters passage conditions as the stem turns and controls fuel movement through the heating circuit at the selected setting.
