Abstract: A gas valve for a gas appliance of a gas burner system. The gas valve is connected to a gas source via a gas pipe. The gas valve is disposed with a check valve body, wherein the check valve body allows gas in the gas pipe to flow into the gas valve and prohibits the gas in the gas valve to flow into the gas pipe so the check valve body can thereby prevent the gas in the gas valve from flwoing back to the gas pipe. When gas in the gas pipe flows to to another gas appliance of the gas burner system, the gas flowing to another gas appliance does not mix with air in the gas appliance, thereby reducing the iginition time and enhancing the combustion efficiency.
