Knife Gate Valves employ a sharp-edged gate that cuts through slurries, suspended solids, and viscous fluids with guillotine shearing action unavailable in traditional wedge gate valves. This design dominates African mining, wastewater, and pulp & paper applications where abrasive slurries, fiber suspensions, and solids-laden flows would jam or damage conventional gate valves requiring wedge-to-seat contact for sealing.
Serving African slurry transport from Zambian copper mines to South African gold operations, knife gate valves handle DN 50 to DN 1200 (2″ to 48″) abrasive service in Class 150-300 or PN 10-16 ratings. The thin knife-edge gate slices through settled solids during opening while full-port design enables unobstructed flow when open—essential for mining tailings lines, mineral processing slurries, and wastewater treatment systems where conventional gate valves would clog.
