The triple function air valve is installed at the pump outlet or in the water supply line to remove a large amount of air from the pipe or discharge a small amount of air collected at a higher level of the pipeline into the atmosphere, so as to improve the efficiency of the pipeline and the pump. Once in case of negative pressure inside the pipe, the valve will quickly absorb the outside air to protect the pipeline from damage caused by negative pressure
