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.
