 PTFE Lined Plug Valve

  • The design is Bi-Directional and through the use of a sealinggroove, zero leakage is achieved.
  • The sealing groove fixes the liner inside the valve and also absorbs mini-deformation of the liner due to temperature
  • changes. Simultaneously, the groove serves to clean and lubricate between the Liner and Plug, thereby improving the sealing and valve life.
  • The design of the top bearing with PTFE gasket and O-ring with adjusting gasket, allows flexibility of the Plug position to ensure sealing of the plug liner and also the outside seals.
  • The full sealing process is almost independent of line pressure.
  • Different Teflon lining material is available to suit temperature and medium handled.
