About TEKO flange end butterfly valve


Our PTFE liner makes it a great and effective solution for a wide variety of industrial applications. The butterfly valve of this type offers quick opening and closing with full flow in either direction and leak tight shut off. Flange gaskets are not required because the lining that extends onto the faces acts as a gasket.



  • Body of stainless steel, Carbon steel, Cast iron
  • Disc: Stainless Steel (CFM8), Lined WCB
  • Seat: PTFE PFA, FEP, Rubber etc
  • Stem: Stainless Steel

Features & Benefits

  • Substantial PFA/PTFE liners for 3" through 40"
  • Benefit is resistance to permeation leading to extension of product life and operator safety because of lack of atmospheric leakage.
  • Live loaded stem sealing system. Benefit is atmospheric sealing integrity and no manual adjustment over the life of the valve.
  • Low torque. Benefit is smaller operators taking up less space, ease of operation and cost savings with less expensive automation packages.
  • Improved disc design leading to less deflection at higher pressures and tighter in-line seal
  • ISO 5211 Actuator Mounting Pad for standardized actuator mounting
  • Live loaded self-adjusting shaft seal with triple O-ring protection
  • Blow-out proof shaft design for additional operator safety
  • Extended body and disc liner above the shaft seals provide optimum protection of the O ring shaft seals from corrosive media
  • PTFE atmospheric seal protects internal components from atmospheric corrosion and provides locating ring for actuator mounting
  • Fully encapsulated bottom shaft eliminates potential leak path at bottom of valve and eliminates the necessity for further sealing elements
