  1. The integral type welded ball valve,there will be no leakage at all.
  2. Due to the seat is made of carbonize teflon (C-PTFE)and spring,so it has a strong adapt for the change of the pressure and temperature,there will be no leakage within the state pressure and temperature
  3. The manufacture of the ball tracked and checked by advanced The computer monitor,so the balls have been precisely machined
  4. The material of the valve as same as the pipe,there will be no uneven stress,also will not be deformed due to the earthquake and pass by cars.
  5. Directly buried type welded ball valve can be buried under the ground directly and not need to High large valve shaft,just need Small shallow Wells ,this save a lots of cost and process time.
