Slurry Knife Gate Valve

Category:

Handling abrasive and high-solids process materials requires a valve designed to withstand demanding service conditions. A Slurry knife gate valve Manufacturer in Canada provides dependable on/off isolation for pipelines transporting mineral slurries, tailings, sludge, ash, wastewater, and other solids-containing fluids.  

Its gate moves through the flow passage to separate the process material and close the line, while the valve construction can be selected to suit abrasive and corrosive operating conditions. These valves are widely used where durability, effective solids handling, and reliable shut-off are essential. 

Features and Applications 

  • Sharp-edged gate for cutting through slurry and suspended solids 
  • Full-port flow passage in applicable designs 
  • Abrasion-resistant construction for demanding slurry service 
  • Low flow resistance in the fully open position 
  • Resilient or metal seat configurations 
  • Unidirectional or bidirectional designs, depending on configuration 
  • Mining and mineral processing 
  • Slurry and tailings handling 
  • Water and wastewater treatment 
  • Power generation and ash handling 
  • Chemical and process industries 
  • Cement and mineral processing
