ZSK Series Wear-Resistant pulp valve 

The SK Series wear-resistant combined slurry valve overcomes the limitations of conventional flat gate valves that can only handle a single medium (oil or water). It provides reliable sealing performance in both fully open and fully closed positions. This valve is a high-tech, high-quality product with low flow resistance, compact size, simple structure, and dependable operation.

It is widely used for slurry transportation of granular materials in mining, power plants, metallurgy, chemical industry, and other sectors—especially in medium and high-pressure slurry pipelines. It is an ideal replacement valve for slurry pipeline applications. 

 

KEY FEATURES:

  • Two-piece valve body.
  • Standard Wafer design.
  • U-shaped sealing.
  • Integral ultra-thin body structure.
  • Knife gate provides strong shearing force.
  • Reasonable and robust structure.
  • Easy operation and long service life.
  • Excellent wear resistance and pressure resistance.
  • Wearable parts can be replaced quickly.
  • Easy to assemble and maintain.
  • Low maintenance cost and high cost-effectiveness.
  • Avoids the problem of gate galling or “gnawing”.
  • Reliable sealing performance.
  • Sealing gap is easy to adjust.
  • No sedimentation in slurry conveying systems.
