First, D71F46 manual pair of lined with fluorine butterfly valve Brief introduction
Lining fluorine butterfly valve with a spherical sealing surface of the lining of the fluorine plastic package liner plate, together with the base of the silicone rubber liner to adjust the sealing performance of the valve; the valve operation light , Tight sealing performance, long service life; can be used to quickly cut or adjust the flow of use. Suitable for applications where reliable sealing and good adjustment characteristics are required. The valve body adopts the split type, and the seal of the valve shaft is controlled by the rotating base surface between the butterfly plate and the valve seat, so as to achieve the compact product structure, beautiful appearance, reasonable process and reliable performance. To ensure that the valve shaft is not in contact with the fluid medium, replace the valve shaft is very convenient, the valve does not need to be separated from the pipeline to complete. Products are widely used in a variety of different types of industrial pipelines in the liquid and gas (including steam) delivery, especially with severe corrosive media such as sulfuric acid, hydrofluoric acid, phosphorus, acid, LU gas, strong alkali, Such as a strong corrosive medium.
