Clarkson Model KGA

Clarkson Model KGA

The Clarkson KGA slurry knife gate valves feature heavy-duty, full port elastomer sleeves offering the ultimate isolation against heavy slurries.

Applications include:

  • Mining
  • Power
  • Pulp and paper
  • Alumina
  • Chemical
  • Cement


  • Meets a wide range of abrasion, corrosion, temperature, and pressure requirements. 
  • May be used in wet or dry services easily dealing with large, heavy particles and tramp material. 
  • 100% isolation; bubble-tight shut-off results in absolutely zero downstream leakage. 
  • Heavy-duty, field replaceable elastomer sleeves with internal stiffener (U. S. patent 5,271,426). 
  • Double-seated design provides bi-directional flow and shut-off. Unobstructed flow eliminates turbulence, minimizes pressure drop across valve.
  • No seat cavity where solids can collect and prevent full gate closure.
  • No gate or stem packing is required, eliminating packing leakage and maintenance. 
  • Adaptable frame (yoke) design featuring a top-removal stem nut.
