Ceramic Knife Gate Valve

Featuring structural ceramic-lined surfaces on all wetted components, this valve provides exceptional resistance to scouring, erosion, and chemical attack — significantly outperforming standard metal valves in abrasive service. Its precision knife gate design cuts cleanly through slurry media, preventing solids build-up, sticking, and valve failure that commonly affects conventional gate valves in these applications.

Designed for unidirectional sealing with a single seat configuration, the valve delivers consistent shut-off performance while eliminating the accumulation of ash residue and fine solids that compromise valve integrity over time.

• Surface sealed with structural ceramic to resist scouring and abrasion
• Single seat design to prevent sticking and accumulation of ash residue
• Single seat and unidirectional sealing with pressure

• Suitable for the conveying system with liquid-solid two phrase medium, such as ash, slurry, mine residue, coal residue and sewage, expecially useful for the heavy medium system of coal mill.
