Key features/benefits

  • Field replaceable thick elastomer sleeves are easily replaced without disassembling the valve
  • Sleeves are available in a variety of materials to handle abrasive and corrosive applications
  • Full port flow reduces pressure drop and turbulence, thus minimizing wear
  • Bi-directional shut off, 100% bubble-tight shut off
  • Packingless design
  • No gate or stem packing
  • Open bottom allows for the purging of large solids, and solids in high concentration
  • Yoke design allows fitting for all designed actuators
  • No seat cavities where solids can collect and cause gate interference
  • May be used in wet or dry application
  • Flush control option allows for periodic cleaning of the lower discharge vent and allows flushing as needed
