YFL PFA lined diaphragm valves and PFA lined lift type check valves are exported to Moroco in Africa for corrosive service.

The PFA lined diaphragm valves are produced according to BS EN1561.

The carbon steel body is lined with PFA material, which is corrosion resistant against almost all corrosive service. There are two diaphragms, the lower one is made of PFA and the upper one is made of EPDM. With the diaphragms, the bonnet and stem won't contact with the corrosive service. The PFA diaphragm protects the bonnet and stem from corrosion.

The PFA lined lift type check valves are used to stop the backflow of corrosive medium. The body, bonnet and disc are fully lined with PFA material to be corrosion resistant. When there is backflow, the disc will close automatically to avoid backflow and protect the pipeline equipments.
