General Handling Precautions Exposure to contaminated high temperature compressed air may deteriorate packings or other components making the valve life shorter 9 3 Piping 1 Use galvanized pipe for steel tube piping and remove dusts after screwing 2 Before connection clean the pipes by air flushing or washing to remove internal dusts moisture and oil 3 If a seal tape is used for screwing wrap the tape around twice or three times in a direction opposite to the screwing direction leaving 1 5 to 2 threads from the screw edge 4 When screwing pipes and joints into a valve use an appropriate size of wrench and fasten the pipes and joints to the extent not causing air leakage Forceful screwing may result in cracking of the valve connection port or leakage malfunction due to contamination with fragments of sealing materials 5 In case of 6A to 25A Rc1 8 to 1 size pipes or joints 4 to 5 threads should be screwed An exercise for seal tape wrapping and screwing before actual work is recommended 6 A valve especially large size valve should be fixed not only with the piping but also with supporting components For some mini size solenoid valves with steel tube piping supporting components may be used for the piping portion In this case sufficiently support around the valve with piping clamp and other components AN Caution Electrical circuit and piping 1 Reconfirm that the voltage and current AC or DC of power
