F46 Lined Ball Valve,FKP Lined Valve,PFA lined ball valve,Teflon Lined Valve
It shall keep up with the international product in same industry to adopt the new FK/FKP series ball valve of integrated bellows stem se-al system.
The design concept of FK product series is to provide adaptive solutions for various applications.
The leak tightness of FK ball valve is proved to comply with the regulations of state standard (GB/T13927).

Integrated ball/valve stem with anti- expulsion design.
The lining of valve and ball can provide the general chemical corrosion-resistance materials as PFA & FEP by requirements.
As for the innovative plate-type PTFE bellows filling structure, it can automatically adjust between the movable filling gland ring and spring tableting, and even though under the condition of heat-cool cycle, the filling always has high leak tightness and reliability for preselection loading.

Even though on condition of frequent alternation between coldness and heat, it can realize the sealing effect for the flange of metal to metal mode.
It has unified lining thickness in the sealing area to promote the ability for resisting the permeable media.
Strengthen the surface loading ability for labyrinth sealing through casting sealing lip.
Carry long life PTFE valve seat
It adopts special spring valve seat design to ensure permanent leak tightness within the range of the entire pressure/temperature, including in condition of vacuum.
