Teflon Lined Ball valve  ★★★★★
  • B55F
  • Series B55F Teflon lined ball valve with its body and ball full encapsulated by PFA, FEP or PTFE is for top corrosion medium with high reliability and safety.

    FEATURES
    . Exchangeable PTFE seat rings.
    . Dovetail grooves machined into the body ensure locking of the lining to the body and reduce the effect of liner loading at the flanges.
    . Metal to metal body joints ensure lining not squeezed out by pressure or thermal cycling.
    . One piece Ball/Stem design for both regulating and shut off(B55F1), two piece Ball/Stem design for pressure up to 25bar(B55F2).
    . Self adjusting packing of V-rings by a permanent spring loading provides stem seal integrity while maintaining low turning torque.
    . Full port flow path is designed for minimum pressure drop.
