Fluorine lined ball valve is a special type of ball valve whose internal key components (such as the ball, the seat and the inner wall of the body) are lined with fluorine plastics (such as PTFE, FEP, etc.) to provide excellent corrosion resistance.

Ball valve basic series Q41F46, can be divided into two parts (two pieces) and three pieces of two structural forms, in addition to the general ball valve has the fluid resistance of small, fast opening and closing speed, simple structure, there are the following advantages:

1. Ball valve with FEP lining layer, with high chemical stability, can be applied to any other strong corrosion properties except "molten alkali metal and elemental gas";

2. With full diameter and floating ball structure, the valve can be closed without leakage in the entire pressure range, which is more convenient for the pipeline system to pass the ball line sweeping and pipeline maintenance.

3. The ball of the opening and closing part and the valve stem casting (forging) are integrated, which eliminates the possibility of the valve stem rushing out of the pressure part due to pressure changes, and fundamentally ensures the safety of use in the project;

4. Compact and reasonable structure, the body cavity space is minimal, reducing the medium retention, in addition, the special molding process, so that the sealing surface density is good, coupled with the herringbone PTFE packing combination, so that the valve to achieve zero leakage;

5. The two-piece, three-piece structure can adapt to a variety of different requirements of the pipeline system and working conditions, of which the three-piece ball valve allows the main valve body to be separated from the valve body on both sides, which can realize online rapid replacement and maintenance.
