Slurry Knife Gate Valve
Slurry Knife Gate Valve – Hardened Construction for Severe Abrasive Service
Slurry Knife Gate Valves feature specialized abrasion-resistant materials including Ni-Hard bodies, hardened gate edges, and wear-resistant seats designed specifically for severe abrasive service in African mining slurry transport, mineral processing, and copper/gold tailings applications. Hardness ratings of HRC 58-64 provide 5-10× service life versus standard carbon steel in erosive slurries with suspended solids.
Dominating African abrasive slurry service from Zambian copper concentrates to South African platinum processing, slurry knife gate valves serve DN 50 to DN 1200 (2″ to 48″) mining duty applications in Class 150-300 ratings. The hardened construction withstands continuous erosion from quartz, pyrite, and mineral particles while maintaining guillotine shearing action through settled solids—critical for African mining operations where premature valve wear directly impacts production uptime and maintenance costs.
