A gas valve regulates the flow of natural gas or propane to appliances like furnaces, boilers, water heaters, and ranges. It can be manual or automatic, opening when the appliance calls for heat and closing to stop gas flow when heating is complete or a fault is detected. Gas valves are essential for safe combustion and reliable operation.
