Larox Flowsys has launched a new series of valves to supplement the pinch valve family. The Larox heavy-duty knife gate valves are engineered to be used in tough environments with demanding media in the same industrial applications as the company’s well known pinch valves. Larox knife gate valves are built with a cast body and feature a stainless steel gate. Removable seats on either side of the gate provide a bi-directional bubble tight seal, with no metal parts in contact with the slurry when open. The knife gate valves are suitable for applications that involve abrasive or corrosive slurries, powders or coarse substances. One of the benefits that these valves have is that the metal parts of the valve are not in contact with the slurry when open, only the 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. Double seated design provides bi-directional 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.
