Features and Benefits

  • No Leakage
    Bubble-tight sealing is provided even at low-pressure differentials.
  • Low Pressure Drop
    Large passgeways provided flow chararcteristics with lower pressure drop than competing valves.
  • Non-Sticking
    The free-floating seat and poppet design prevents sticking due to canting of the disk member. PTFE used in seats and poppets is self lubricating and resistant to corrosion.
