Knife Gate Valves
Slurry and bulk-media isolation

Knife Gate Valves
Overview
Knife gate valves are purpose-built for thick, fibrous and abrasive media. A sharp-edged gate cuts through slurry to give clean isolation in a compact, lightweight body — widely used in pulp & paper, mining, sugar and effluent applications.
Key Features
- Cuts through slurry, fibre and bulk solids
- Compact, lightweight wafer body
- Uni- and bi-directional designs
- Manual, gear or pneumatic operation
- Replaceable seat and gland packing
Applications
Pulp & paper Mining Sugar Effluent / wastewater Cement
