DeZURIK Slurry Knife Gate Valves (KSL-LA) Long Body Design

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
• Full flanged design with flange drilling per ASME B16.5 Class 150, DIN and BS standards, PN10 and PN16, and SANS 1123-1000 and 1600 Australian Table D & E (AS 2129) available.

•  

  Body construction allows for easy repairs.
• Sleeve design eliminates gate and stem packing.
• Straight vertical plane superstructure allows for easy installation of accessories.
• Open / Closed position lock-outs optional.
• 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 12" (300mm) and larger.
• Flushing drain plates available.
