The operation of the valve for air charging is like as charging a car
tire.Disassembling the protective cap on the end flange, put a pressure gauge upon the screw-joint coupling,
the pressure gauge shows the data to be the internal pressure.
If internal pressure being higher than desirable figure,
a discharge operation must be need as follows.
