Larox's knife gate valves are engineered to be used in tough environments with demanding media.

They are built with a cast body and feature a robust stainless-steel gate.

Removable seats on either side of the gate provide a bidirectional bubble-tight seal, with no metal parts in contact with the slurry when open.

Larox Flowsys has launched three knife gate valves for heavy slurries: Larox flanged knife gate valve (LKF), Larox high-pressure knife gate valve (LKH) and Larox wafer knife gate valve (LKW).

More product additions are to be introduced soon.

The knife gate valves are ideal for applications that involve abrasive or corrosive slurries, powders or coarse substances.

Larox said a benefit of these valves is that the metal parts of the valve are not in contact with the slurry when open - only the easily replaceable rubber ring sleeves or secondary seals touch the medium.

The ring sleeves and seals are placed in the valve housing to seal against the gate when the valve is closed and seal against each other when the valve is open.

This tight seal contains the high internal line pressure.

The double-seated design provides bidirectional flow and tight shut-off.

Any material/medium discharged between the sleeves during stroking open or closed is collected within the containment area of the valve body and drained via the multiple flushing ports in the body.

The Larox knife gate valves are produced with manual, manual gear, pneumatic, hydraulic and electromechanical actuators.
