The knife gate operates like a gate valve, but the gate has a sharp bevelled edge that slices through slurry, fibres, and solids rather than attempting to push them aside. The gate slides into a rubber sleeve seat (replaceable without removing the valve from line) or a metal seat.
Rising stem design provides immediate visual position indication. The full bore design when open prevents settling and blockage in heavy slurry service.
