GMK PFA lined butterfly valve comprises a body, stem, handle, and butterfly disc in addition to the polymer coating that it has on its outside. A central axis serves as the connection point between the disc and the stem and handle. You can open and close this valve by spinning the disc that is contained inside the valve in a horizontal direction. When the disc is in a position that is parallel to the pipeline, the valve is open, and when the disc is in a position that is perpendicular to the axis of flow in the pipeline, the valve is closed.


  • This product has increased longevity, and the working environment is made safer, thanks to the barrier’s resistance to the penetration of GMK PFA lined butterfly valve flange type.
  • It has a stem sealant with a live load. There is no need to adjust the valve by hand, and the seal will remain airtight for the duration of the valve’s service life.
  • It has simplified controls, and lower overall costs are all advantages of this product.
  • The discs’ have improved design and they deflect less under pressure, and the in-line seal is tighter.
  • It has Improved worker protection thanks to a shaft design that cannot be blown out.
  • There is no leak route and no need for additional sealing components.
