  • Improved secondary seal: Capable of being lubricated without disassembly, simplifying valve maintenance.
  • Double-seated design: Provides bi-directional flow and shut-off, ensuring 100% isolation and zero downstream leakage.
  • Unobstructed flow: Eliminates turbulence and minimizes pressure drop across the valve while preventing solids from collecting and obstructing gate closure.
  • Full flange body design with available flange drilling including ASME B16.5, PN10 & PN16 (per DIN and BS standards), and Australian Table D & E (per AS 2129) among others.
  • Simplified two-piece body design allows for easier rebuilds.
  • Higher optional pressure rating possible with selected gate materials, can be rated up to 200 psi
  • Meets a wide range of abrasion, corrosion, temperature, and pressure requirements.
  • Can be used in wet or dry services easily dealing with large, heavy particles and tramp material.
  • 100% isolation; bubble tight shut-off results in absolutely zero downstream leakage.
  • Heavy duty, field replaceable elastomer sleeves with internal stiffener
  • No seat cavity where solids can collect and prevent full gate closure.
  • No metal parts in contact with the flowing slurry.
