Halstead Lpg Boiler Gas Valves
The gas valve is a mechanism used for gas distribution. When there is an increased need for gas in the burner, a message is sent from the printed circuit board to the gas valve, which opens and allows gas to flow through the valve in to the pilot assembly or the burner dependant on the model of the appliance installed.
