  • The structure is simple, the weight and volume are relatively small, and it is easy to disassemble and repair.
  • Since the valve stem only rotates, the packing seal of the valve stem is not easily broken, and the sealing capacity increases as the medium pressure increases.
  • The fluid resistance is small, and the full-bore ball valve has substantially no flow resistance. Pneumatic ball valves are one of the least fluid resistances in all valve classifications.
  • The operation is simple and rapid, and it only needs to be rotated by 90° from full opening to full closing, which is convenient for long-distance control.
  • It is suitable for a wide range of applications, from a few millimeters to a few meters, from high vacuum to high pressure.

  • The ball valve must be cleaned and repaired once a year.
  • 2 The ball valve should be activated at least once a month to prevent the ball from getting stuck.
  • 3 The ball valve can only be fully open or fully closed and cannot be used for throttling.
