1、 Introduction to ZRHCF electric fluorine lined regulating valve
ZRHCFElectric fluorine lined regulating valveIt is a bellows sealed single seat regulating valve, which uses high-pressure injection molding technology to contact the medium and is lined with corrosion-resistant media such as hydrochloric acid, sulfuric acid, nitric acid, hydrofluoric acid, and aging resistant polytetrafluoroethylene F46. It also uses polytetrafluoroethylene bellows sealing and is widely used in various processes for process control of highly corrosive media such as acid and alkali, as well as toxic and volatile gas and liquid media.
