Johnson Controls H43BA-2 Pilot Safety Valve W/Reducer Bush 1/2" X 3/4" FPT In/Out

The Johnson Controls H43BA-2 Pilot Safety Valve with Reducer Bush IN/OUT regulates gas flow to the pilot burner and automatically shuts, off the supply if the pilot flame runs out. It works through a temperature-sensitive safety mechanism that detects flame presence and controls gas passage between connected fittings. This valve is typically installed within commercial gas-fired cooking equipment, heating systems or burner assemblies where pilot flame monitoring and gas shutoff operations are required. The unit includes 1/2" x 3/4" FPT inlet and outlet connections with a reducer bushing for compatibility with particular gas line configurations and controlled fuel supply applications.
