LIDON VALVE's Ceramic Knife Gate Valves, also recognized as slurry gate valves, are characterized by a straightforward design. They effectively isolate mediums containing solid particles and fibers. In contrast to conventional metal-seated knife gate valves, which may erode easily when dealing with extremely hard particles or aggressive mediums, ceramic knife gate valves prove highly suitable. Their resilience makes them ideal for handling mediums that include fibers and resilient solid particles.

Ceramic Knife Gate ValveCeramic Knife Gate Valve

Characteristics:

1. Sealing surface materials: structural ceramics or super-hard surface alloy materials.

2. It is suitable for gas and solid mixed media such as cinder and ash. The gate, valve seat and flow channel are made of structural ceramic materials, which are wear-resistant and have a long life.

3. Excellent sealing performance, and the sealing surface can be repaired.

4. The imported valve seat can be used as a dust scraper and can be closed freely even in the presence of dust.

5. The valve body cavity structure completely avoids the problems of jamming and dust accumulation.

6. Driving mode: manual, pneumatic and electric, etc.

Application

Ceramic Knife Gate Valves are well-suited for conveying systems involving two-phase mediums, either liquid-solid or gas-solid.

  • ash, mine residue and coal residue in iron and steel plant
  • ash conveying system of power plant
  • paper pulp in paper industry
  • sewage and slurry in decontamination plant
  • the heavy medium system of coal mill.
