PTFE lined butterfly valve is a high-performance valve widely used in the industrial field. It usually uses stainless steel or carbon steel as the valve body material, and the internal coating uses PTFE or PFA .It has strong chemical stability and can resist the erosion of acids, alkali, oxidants and other corrosive media.
This design can effectively isolate the medium from the metal parts, thereby avoiding corrosion problems and extending the service life.
This type of valve adopts a fully enclosed sealing design to ensure zero leakage under high pressure and complex working conditions. This sealing method not only improves the reliability of the valve, but also reduces maintenance requirements.
It is usually equipped with a hand wheel or electric actuator to facilitate flow adjustment and control of the switch state. In addition, this design makes the valve easy to install and maintain, while supporting automated control.
1.All parts are covered by fluorine material, such as PTFE or FEP, which completely prevents corrosion of metal parts by corrosive media.
2.The valve seat filled with rubber has good elasticity, is easy to operate, has a long life, and has better sealing.
3.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.
4.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.
5.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, phosphoric acid, chlorine, strong alkali, etc.
