Bi-directional Seal Full Bore NR Sleeve Carbon Steel Slurry Knife Valve With SS Knife


The TEKO Slurry knife gate valve is developed with years of application and experiments. It is used for most serious applications: mining, power, pulp & paper, Alumina, Phosphates etc. It has features of bi-directional seal, full bore, and easy installation and maintenance.


How the sleeve works


The TEKO slurry knife valve sleeve is well suited for slurry services. The face and seal profile allow easier installation and can be used in most pipe style and mating flange configuration without gaskets. Matching sleeves are placed in the valve housing to seal against the gate when the valve is closed and seal against each other when the valve is open. When open, the improved sleeve ID profile and the sleeve compression combine to provide a tight seal, containing the internal line pressure and precluding direct pressure against the secondary seal.

As the gate moves from open to closed, a gap is creating between the facing sleeves, allowing any media that could potentially clog or jam the valve to be purged out from between the sleeves, and potentially expelled outside the valve housing to atmosphere.

When the gate is fully closed, the sleeves are in full contact with the gate face. Again, the sleeve profile provides an assist to the sealing function. The unique TEKO sleeve assembly provides positive sealing action when the valve gate is closed or open; protecting the metal parts from the flowing slurry.



Carbon Steel Slurry Knife Valve Bi - directional Seal Full Bore NR Sleeve 0


Open position

  • Gate positioned above seals
  • Tight fit between sleeves and the internal sleeve profile contain the line pressure
  • Metal parts not in contact with slurry
  • Unobstructed port area eliminates turbulence, minimizes pressure drop across valve
  • No seal cavity where solids can collect and prevent full gate closure


Closed Position

  • Gate travels through sleeves to provide blind flange shut off and expel solids, allowing complete closure
  • 100% isolation-bubble tight shut-off results in absolutely zero downstream leakage
  • Double-seated design provides bi-directional flow and shut-off
  • Sleeve profile and tight fit between sleeves and gate contains internal pressure
  • Controlled stroke prevents gate from penetrating too far, minimising stress on sleeve
