Wafer/Flanged Carbon Steel Ceramic Lined Slurry Knife Gate Valves are specifically designed as slurry gate valves. Featuring a simple yet robust structure, they are engineered to cut off media containing solid particles and fibers. While general metal-seated knife gate valves often fail under serious erosive conditions or when handling very hard particles, ceramic-lined versions are highly effective for media containing fibers and hard solid particles.

These valves are ideally suited for conveying systems handling liquid-solid or gas-solid two-phase media. Key applications include:
• Ash, mine residue, and coal residue in iron and steel plants.
• Ash conveying systems in power plants.
• Paper pulp in the paper industry.
• Sewage and slurry in decontamination plants.
• Heavy medium systems for coal mills.
