The PFA PTFE lined globe control valve is produced by high temperature molding lined fluoroplastic process in the valve body wall and the valve trim.It can completely cut off the contact between the corrosive medium and the valve body,then it enhances the service life of valve.The PFA PTFE lined control valve is widely used for acid, alkali, salt and other strong corrosive medium,also used for gas and liquid medium that are easily volatilize and penetrate.
