Teflon lined valve is to set the teflon eight er inside the cast iron or cast steel valves，or stick it on trim's surface by moulding pressing，we using teflon's particular properties in strong corrosion resistant to produce many kinds of valves and pressure vessels.
    Teflon's popular name is"King plastic"，Firstly developed by American DUPONT CO.，LTD in 1938 and firstly used in the industrialization production In 1949.It has been used for more than 50 years in industrial applications，but not longtime used in valve industry.
    In corrosion resistance materials，teflon has its super nice performance.it can not only dissolved to alkaline metal，F1uorine，aromatic hydrocarbons but also follow with others natural response while meet HCL，He SO 4，aqua regia，organic acid，strong oxidant，alte mate thick and thin acid，alkali.Sticking teflon inside valve's body，it can conquer the teflon's problem of low intensity，furthermore，its oved the problem of the body material in high cost but poor corrosion resistance.In addition，except the stable chemical specification，teflon has its other merit such as antifouling，sticky-safe，Iow friction coe fficient.
    With the speedy development of industry，teflon lined valves will widely used in petroleum，printing，chemical industry and soon with its Vigorous vitality.As a first choice for project，more and more attention takes by design institutes and construct institutes to this strong market potential product teflon lined valves.
    We center on the field of teflon lined valves for so many years，after wide market diagnoses and throgh the unceasing efforts of the technicians，8 kinds of the products wth unique form have been researched and developed，such as teflon lined butter ily valve，cock valve，ball valve，globe valve，check valve，dai phrag m valve，gate valve and soon，with 10 pressure classes and more than 1120 specifications Except the lining of PTFE(F4)、RPTFE(RF4)、FEP(F46)、PFA，PVDF，we add PO，PE，PP and PVC to cater to diferent using demand.
    Our staffs always takes"orient by market，develop by technology."as the guidelines，making more efforts and researches constantly to return our customer by better and better corrosion resistance valves.
