Manual knife gate valves are designed for shut-off applications involving slurry, pulp, sludge, wastewater, and other solids-containing media. The knife-edged gate moves through the flow path to help cut through fibrous materials and reduce clogging during valve closure.
Operated by a handwheel with a rising-stem mechanism, the valve allows direct manual opening and closing without electricity or compressed air. This makes it a practical choice for local pipeline isolation, maintenance operations, and systems requiring occasional valve operation.
Flanged, lugged, and wafer connection options are available for different piping arrangements. Metal-seated and PTFE seat configurations, along with carbon steel and stainless steel body materials, allow the valve to be matched to different media and operating conditions.
Typical applications include wastewater treatment, pulp and paper production, mining slurry pipelines, and industrial sludge or ash handling. VINCER also supports customized materials, sizes, and connection requirements for specific projects.
