Slurry Handling

Krebs Technequip Knife Gate Valves

The Krebs Technegate™ knife gate valve is a bi-directional, packingless, on-off slurry knife gate valve designed for harsh service.

  • Slurry Knife Gate Valve

Technequip knife gate valves are designed specifically for abrasive slurry applications.

Sleeves
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.

Seat
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.
