Double Air Valves ensure that air in the pipe will be automatically evacuated when pipeline is filled with water. Air is evacuated quickly so that water will not make back pressure and affect flow negatively. When water in pipeline is drained, air enters into pipe quickly in such a way that it will not create vacuum. It is proposed that double air valve will be used for maximum efficiency. Generally it is used in pump downstream; automatic irrigation controller upstream and in elevation differentials emerged by referring water source.
