3.More reliable way of discharge
Quick released air and air with water will not close valve orifice in advance and cause air seal,Orifice will close when air is released completely
4.Automatic protection safer performance
Whenever if system pressure is lower than atmosphere ,water column happened,the air relief valve will open immmediately and air will enter system to get rid of negative pressure,at the same time,entering air can speed up the speed of air release during air release
