Application

Disc, lightweight operation of the valve, tight sealing performance, long life; can be used to quickly cut off or regulate the flow purposes. For applications that require a reliable seal and good regulation characteristics of the occasion. Body using split, seal the ends of the valve shaft by the rotating disc and seat base between fluoride rubber to control; ensure that the valve shaft is not in contact with the cavity fluid medium. Widely used in various types of industrial pipeline liquids and gases (including steam) delivery, there is a serious corrosive media occasions, such as: sulfuric acid, hydrofluoric acid, phosphoric acid, chlorine, alkali, aqua regia and so has strong corrosion of media.
