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.
