The LN6131F plastic lined control valve not only has reliable sealing performance, but also has the unique advantage of being resistant to strong corrosive media such as hydrochloric acid, sulfuric acid, hydrofluoric acid, and alkali. The inner wall of the valve body and the components inside the valve that come into contact with the fluid are lined with corrosion-resistant and aging resistant perfluoroethylene propylene (FEP). The valve is equipped with a corrugated pipe component, and the top of the valve core is sealed and connected to the upper end of the PTFE corrugated pipe. The lower end of the corrugated pipe is tightly sealed and connected to the valve body, upper valve cover, and support with bolts and nuts. The corrugated pipe isolates the medium from the outside world. Adapt to regulating room temperature and atmospheric pressure media that are highly corrosive, toxic, valuable, volatile, and permeable.
