Lined Butterfly Valve

Overview AEAD lined butterfly valve is adopted lined plastic procedure and lined with 2~3mm fluoroplastic (F46 or PFA), which has the characteristics of good corrosion resistance, quick opening and closing, long service life and less leakage. The valve can be equipped with pneumatic cylinder or electric actuator to meet several of requirements of controlling, and it is used widely for controlling, cutting off and remotely controlling in the site of chemical industry, petroleum, metallurgy, medicine, electric power, environmental protection and so on. Features 1. Both cavity and disc are lined F46 or PFA, which can be proof of almost all the corrosive medium and long time of permeating chloridion. 2. The soft seat will be deformed properly to ensure the zero leakage when the valve is closed. 3. The disc and stem are made as a whole, the PFA bearing is used not only for guiding but also for good lubrication. 4. There is mechanical seal between disc and seat ring, which ensures no permeating around stem. 5. Soft material lined butterfly valve is of small torque, which has good performance of opening and closing. 6. The substrate of soft material lined seat ring is formed by rubber injection. 7. Flexible compound material is used and the compound seat ring of rubber and PTFE will be properly performed when the valve is closed, which ensures zero leakage, good reciprocation performance and long service life.
