1. Concentric Fluoroplastic Lined Resilient Seated Lug Type Butterfly Valve adopts lug flange structure with full fluoroplastic lining inside valve body.
2. Concentric disc presses against fluoroplastic lining to achieve bidirectional resilient sealing and resist strongly corrosive media.
3. Fluoroplastic lining material can be selected according to medium temperature and corrosion severity.
4. Widely used in pickling and strongly corrosive chemical process pipelines.
1. Lug threaded holes allow single end installation and removal, opposite flange disassembly is not required for pipeline maintenance.
2. PFA/PTFE fluoroplastic lining resists strong acid, strong alkali and strong oxidants.
3. Bidirectional zero leakage resilient sealing.
4. Short face to face dimension saves installation space.
5. Concentric design delivers moderate operating torque compatible with various actuators.
6. Better chemical resistance than ordinary rubber lined butterfly valves.
7. Suitable for on off and slight modulating service.
