Knife Gate Valve, Slurry Knife Gate Valve


  • High pressure designs for the most challenging applications:
    KGF: 20 bar (300 psi) CWP optional gate provides 31 bar (450 psi) CWP
    KGF-HP: class 300 (51 bar [740 psi] CWP)
  • 100% isolation bubble-tight shut-off results in absolute zero downstream leakage.
  • Double-seated design provides bi-directional flow and shutoff.
  • Field replaceable elastomer sleeves.
  • Dynamic, self-adjusting secondary seal.
  • Unobstructed flow helps eliminate turbulence and minimizes pressure drop across valve.
  • No seat cavity where solids can collect and prevent full gate closure.
  • No metal parts in contact with the flowing slurry.
  • No gate or stem packing is required, eliminating packing leakage and maintenance.
  • Adaptable frame (yoke) design, featuring a top-removal stem nut, can be field modified to an air cylinder or bevel gear in the field.
