V-NOTCH BALL VALVE SERIES 3002

The V–Notch Ball Valve gives non-clogging, high capacity, straight through flow control of fluids containing pulp and paper stock or slurries and fluids containing suspended solids or fibrous materials.

Design Features

  • A Shearing effect between the ball and seal ensures tight shut-off, even on fibrous slurries.
  • The unrestricted, straight – through flow design provides high capacity and wide rangeability.
  • Precise contouring of the V-notch balls provides a nearly equal percentage characteristic.
  • Replaceable ball seal and back up ring for added rigidity.
  • Ball machined to a super smooth finish, hard – chrome plated and polished to increase Ball seal life.
  • High Cv to body size ratio.
