All parts are covered by fluorine material, such as PTFE (polytetrafluoroethylene) or FEP (fluorinated ethylene propylene), which completely prevents corrosion of metal parts by corrosive media.

Features

All parts are covered by fluorine material, such as PTFE (polytetrafluoroethylene) or FEP (fluorinated ethylene propylene), which completely prevents corrosion of metal parts by corrosive media.

The valve seat filled with rubber has good elasticity, is easy to operate, has a long life, and has better sealing.

The center line structure can be used for fast cutting off or adjusting the flow, suitable for occasions requiring reliable sealing and good adjustment characteristics.

The valve body of the PTFE-lined butterfly valve adopts a split type, which is very convenient when replacing the valve stem. The valve can be completed without removing the pipeline.

PTFE-lined butterfly valves are widely used in the transportation of liquids and gases (including steam) in various types of industrial pipelines, especially in the use of heavy corrosive media, such as: sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, strong alkali, aqua regia, etc.
