YFL Anti-corrosive fluorine lined ball valves have body and ball lined with anti-corrosive fluorine materials such as FEP and PFA. The raw materials of FEP and PFA are imported from 3M company in USA and DAKIN company in Japan. Good quality FEP and PFA materials ensure excellent corrosion resistance of FEP/PFA lined ball valves. There are some small holes on the surface of ball to make the FEP/PFA adhere to the ball. The stem and the ball are cast or forged integrally to be better for lining and make sure the stem won't be blowed out. There are O-port ball for cut-off function and V-port ball for regulating purpose.
The body and bonnet of FEP/PFA lined ball valves are machined first to be ready for fluorine lining. And then the ball, seat and other trim parts are assembled.
After assembly, the FEP/PFA lined ball valves need to be done with pressure test before painting. Strict pressure test and spark test ensure the sealing performance and corrosion resistance of the FEP/PFA lined ball valves.
After paining, the FEP/PFA lined ball valves are packed well to be ready for delivery. There are floating ball valves and trunnion mounted ball valves with FEP/PFA lining. The operation ways can be handwheel operated, gear operated, pneumatic operated, electric operated etc. The actuators are equipped with accessories like limit switch, air filter and regulator, positioner, solenoid valves to realize different control requirements.
