1. Fluorine-lined ball valves with FEP lining have very high chemical stability and can be used for any strong corrosive properties other than "molten alkali metals and elemental fluorine".

2. Adopting full-bore and floating ball structure, the valve can be closed without leakage within the whole pressure range, which is more convenient for ball-passing sweeping and pipeline maintenance of pipeline system.

3. The structure of fluorine-lined ball valve is compact and reasonable, the cavity space in the valve body is minimal, and the medium retention is reduced. In addition, the special molding technology makes the sealing surface compact and good, adding herringbone PTFE packing combination, so that the valve achieves zero leakage.

4. The two-piece structure can be adapted to various pipeline systems and working conditions. The three-piece ball valve allows the main valve body and the two side valve bodies to be separated, and can be quickly replaced and maintained on-line.
