    Product introduction:

    D671F46 pneumatic wafer butterfly valve with fluorine lining is composed of PTFE sealing butterfly valve, stainless steel valve plate and valve stem. It is suitable for working conditions where the temperature is ≤150℃, weak corrosion or cleanliness has certain requirements, and it is used as the function of regulating flow and intercepting medium in the water supply and drainage and gas pipelines of food, medicine, chemical industry, petroleum, electric power, textile, papermaking, etc.

    The pneumatic fluorine-lined butterfly valve adopts a PTFE-lined butterfly plate with a spherical sealing surface. The valve is easy to operate, tightly sealed, and has a long service life; it can be used to quickly cut off or adjust the flow. It is suitable for occasions requiring reliable sealing and good adjustment characteristics. The valve body adopts a split type, and the seal at both ends of the valve shaft is controlled by adding fluorine rubber to the rotating base surface between the butterfly plate and the valve seat; to ensure that the valve shaft does not contact the fluid medium in the cavity. Pneumatic wafer-type fluorine-lined butterfly valve is widely used in the transportation of liquid and gas (including steam) in various types of industrial pipelines, and the use of severe corrosive media, such as sulfuric acid, phosphoric acid, strong alkali, aqua regia, etc. Corrosive media.
