Bi-Directional Knife Gate Valve

Bi Directional Knife Gate Valve Supplier in Libya – Slurry Isolation Regardless of Flow Direction

Bi-Directional Knife Gate Valves feature symmetrical sealing that provides tight shutoff against pressure from either direction, eliminating installation orientation concerns in African mining circuits, wastewater systems, and process applications with reversing flows or uncertain pressure differentials. Unlike unidirectional designs optimized for downstream sealing, bidirectional knife gates seal equally well regardless of which side experiences higher pressure.

Critical for African slurry applications with flow reversals—including Zambian copper flotation circuits, South African mining recirculation systems, and wastewater treatment plants—bidirectional knife gate valves serve DN 50 to DN 900 (2″ to 36″) applications in Class 150-300 ratings. The symmetrical seat design enables installation without regard to flow direction while maintaining guillotine shearing action through settled solids, eliminating the need for directional arrows and simplifying installation logistics in remote African locations.
