  • products details

YFL Pneumatic PFA lined butterfly valve adopts butterfly disc as open and close component to cut off or connect the flow by 90 degree rotation with small operation torque. The PFA lined butterfly valve can be also used to regulate the flow by differnt degree rotation.

YFL Pneumatic PFA lined butterfly valve has two-pieces body and disc all lined with PFA or FEP so that the medium only contact with fluoroplastic which is anti-corrosive material against almost all corrosive service. The surface of FEP or PFA lining inside the body is very smooth so that the flow resistance is small and CV value is high. 

YFL Pneumatic PFA lined butterfly valve has center line structure with bidirectional seal. And the smooth sealing face between the body lining and disc lining can achieve excellent tightness with zero leakage.
