Heavy-duty knife gate valves engineered for harsh environments and media
July 27, 2009
The knife gate valves are built with a cast body and features a robust 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. Sizes range from 2-inch to 24-inch with pressures up to 300 psig. The knife gate valves are ideal for applications that involve abrasive or corrosive slurries, powders or coarse substances. 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 knife gate valves are produced with manual, manual gear, pneumatic, hydraulic and electromechanical actuators. Larox manufactures 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).
