Technequip knife gate valves are designed specifically for abrasive slurry applications.
Massive elastomer sleeves are longer than valve bodies, and compression between retainer flanges or companion flanges provides a bubble tight seal. It eliminates the packing gland and provides wear resistance.
The sleeve design allows for an unobstructed full port opening and bi-directional flow.
An open body allows for particles to be flushed away from the gate path.
