Knife Gate Valve

Uses a sharp-edged gate to isolate pipelines carrying slurries, powders, wastewater and other solids-bearing media.

For handling slurries and media with high concentrations of suspended solids, a Knife Gate Valve uses a sharp-edged gate to move through the medium and create a clear opening when fully raised. Knife Gate Valve  supplier In Africa manufactures valves that are commonly selected for applications where solids, fibres or abrasive particles can interfere with conventional isolation valves, including mining, wastewater, pulp and paper, and bulk-material handling systems.
