Technequip Knife Gate Valve


Abrasive Slurry Knife Gate Valves

Krebs Technequip™ Knife Gate Valves

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

Technequip knife gate valves are designed specifically for abrasive slurry applications


The massive sleeves which are longer than the valve bodies compress providing a bubble tight seal resulting in zero downstream leakage.


The sleeve design allows for an unobstructed full port opening and bi-directional flow.

Open Body  

The open body design eliminates the need for a packing gland and allows for particles to be flushed away from the gate path.
