The basic series of fluoroplastic lined ball valves launched by the company is q41f46, which can be divided into two-piece and three-piece structure types. In addition to the small fluid resistance, fast opening and closing speed and simple structure of general ball valves, the company also has the following advantages:

1. The ball valve with FEP lining layer has extremely high chemical stability and can be applied to any other strong corrosive properties except "molten alkali metal and elemental fluorine";

2. Adopt full-diameter and floating ball structure, and the valve can be closed without leakage within the whole pressure range, which is convenient for pipeline system cleaning and pipeline maintenance;

3. The ball of the hoist and the valve stem are cast (forged) into one body, which eliminates the possibility that the valve stem will burst out of the pressure bearing part due to the pressure change, and fundamentally ensures the safety of use in the project;

4. The structure is compact and reasonable, the inner space of the valve body is minimal, and the medium retention is reduced. In addition, the special molding process makes the sealing surface have good density, and the herringbone ring PTFE packing combination makes the valve achieve zero leakage;

5. The two-piece and three-piece structure can adapt to various pipeline systems and working conditions with different requirements. The three-piece ball allows the main valve body to be separated from the valve bodies on both sides, and can realize online rapid replacement and maintenance.
