First, the fluorine-on butterfly valve clip Brief description
Fu fluorine butterfly valve with a spherical sealing surface of the fluorine-coated plastic-lined butterfly plate, together with the base of the silicone rubber gasket to regulate the sealing performance of the valve operation of the light, tight Sealing performance, long service life; can be used to quickly cut off or regulate the flow of use. For applications requiring reliable sealing and good conditioning characteristics. The valve body adopts the split type, and the sealing of the present end of the valve shaft is controlled by the fluorinated rubber on the rotating base surface between the valve disc and the valve seat so as to achieve compact product structure, beautiful appearance, reasonable process and reliable performance. To ensure that the valve shaft is not in contact with the fluid medium in the cavity, it is very convenient to replace the valve shaft. The valve does not need to be detached from the pipe and can be completed. Products are widely used in various types of industrial pipes in the liquid and gas (including steam) transport, especially with severe punishment of corrosive media use occasions such as sulfuric acid, hydrofluoric acid, phosphorus, acid, LU gas, alkali, aqua regia Such as a strong corrosive media.
