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.

Open Body 
An open body allows for particles to be flushed away from the gate path.
