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

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

Seat: 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.
