DeZURIK’s KSL-LA Slurry Knife Gate Valves are designed for on-off (isolation) service for applications consisting of abrasive, high solids content, wet or dry media. KSL-LA Slurry Knife Gate Valves are ideally suited for applications in the mining, power, and aggregate industries.

The KSL-LA Slurry Valve features sleeves of natural rubber or other elastomers that are compressed by sleeve retainers that allow the valve to provide drip-tight shutoff. In addition, the KSL-LA valve features:

  • Bi-directional, drip tight shutoff to full pressure rating.
  • Field replaceable sleeves with encapsulated supporting ring.
  • Full port reduces turbulence and pressure drop across the valve.
  • Sleeve compression eliminates cavity where solids can collect.
  • Sleeve design eliminates the requirement for flange gaskets.
  • Gate fully retracts out of the flow path in the open position.
