Straight-through, non-leakage 90 degree (quarter-turn rotation) valve group. Body structure and closing element are in spherical form and unidirectional sealing in the direction opposite to the pressure.

  • Straight-through, non-leakage 90 degree (quarter-turn rotation) valve group.
  • Body structure and closing element are in spherical form and unidirectional sealing in the direction opposite to the pressure.
  • It can be opened and closed quickly, in semi-open position, it can also be used for flow rate adjustment purposes.
  • In these types with bottom bearings, the compression force affecting the sphere in the closing direction under pressure is balanced by means of these bearings.
  • With the bottom bearing, the soft seats used in both directions are protected against crushing and other deformations.
  • The economic life of soft seat rings is longer than floating types.
  • Lever operated is recommended up to 6″ Class 150, 4″ Class 300, 4″ Class 600. After these sizes, the use of gear box provides convenience in opening-closing operation.
