Description

DeZURIK’s KSL-SD Slurry Knife Gate Valves are designed for on-off (isolation) service for applications consisting of abrasive, high solids content, wet or dry media. KSL-SD Slurry Knife Gate Valves are ideally suited for applications in the mining, power, and aggregate industries. The KSL-SD valve features a short body design with narrow face-to-face per MSS SP-81. Features include:

  • Bi-directional, drip tight shutoff to full pressure rating
  • Field replaceable sleeves with encapsulated supporting ring
  • Valve design allows for easy repairs
  • Full port reduces turbulence and pressure drop across the valve
  • Sleeve compression eliminates cavity where solids can collect
  • Sleeve design eliminates gate and stem packing
  • Sleeve design eliminates the requirement of flange gaskets
  • Straight vertical plane superstructure allows for easy installation of accessories
  • Gate fully retracts out of the flow path in the open position
  • Open / Closed position lock-outs are available
  • Optional gate coatings provide additional abrasion resistance and a non-stick (lubrication infused) surface that reduces actuating forces and extends sleeve life
  • Integral Lifting Lugs standard on sizes 4″ (100mm) and larger
  • Flushing drain plates are available
