The Vaillant gas valve is an instrument used for gas distribution. When there is an increased need for gas in the burner, a message is sent from the electronic control to the gas valve, which opens and allows gas to flow through the valve into the burner or the pilot assembly, depending on the model of the appliance installed.
Comes with shaped gasket and O-rings
