Lined Plug Valves- Precision cast body, plug and cover

FluoroSeal® Lined Plug Valves use investment casting method for the major pressure holding components.

  • All casting components traceable to mill test certificates
  • Investment cast on all materials for sizes 1/2” – 10” (ANSI/ASME Class 150 lbs)
  • Investment cast on all materials for sizes 1/2” – 6” (ANSI/ASME Class 300 lbs)
  • Investment cast on all materials for sizes DN 15 – DN 150 (PN 16 – PN 40)

Corrosion protection

FluoroSeal® standard base model offers Carbon Steel body, plug and cover (ASTM A216 Gr. WCB, 1.0619). Even though FluoroSeal Inc. offers the low porosity PFA as standard, all cast parts have an epoxy-based coating prior to lining for added protection from corrosion attack due to permeation.

Locked-in liner

Lined Plug Valves feature a virgin, unpigmented PFA lining applied by Transfer Molding and locked into castings by machined dove tail shaped grooves, and cast dovetail-shaped recesses in body castings and cast holes. This helps prevent liner collapse in vacuum conditions and blow out in high pressure conditions in conjunction with high temperatures. The Transfer Molding method ensures equal distribution and consistency of liner throughout the entire surface of the lined components. FluoroSeal® Lined Plug Valves comply with the industry specifications (ASTM F1545) dictating the liners’ uniform thickness across the entire valve and guarantee the absence of any weak section in the valve liner. Absence of pigmentation in the PFA renders all defects visible and testifies to FluoroSeal Inc.’s commitment of quality first. The use of virgin PFA reduces stress in the lining which could be caused by the use of regrind in its composition.
