Corrosion-resistant Fluorine-lined Ball Valve
Corrosion-resistant fluorine-lined ball valve
1. Ball valves with fluorine plastic lining have extremely high chemical stability and can be used with any other strong corrosive properties except "molten alkali metals and elemental fluorine".
2. Adopting a full-bore, floating ball structure, the valve can be closed without leakage within the entire pressure range, making it easier for ball cleaning and pipeline maintenance of the pipeline system.
3. The ball of the opening and closing parts and the valve stem are cast (forged) as one body, which eliminates the possibility of the valve stem impacting the pressure-bearing parts due to pressure changes, and fundamentally ensures the safety of use in the project.
4. The structure is compact and reasonable, with the smallest cavity space in the valve body, reducing medium retention. In addition, the special molding process makes the sealing surface dense, and the herringbone annular PTFE packing combination allows the valve to achieve zero leakage.
5. Two-piece and three-piece structures can adapt to various pipeline systems and working conditions with different requirements. Among them, the three-piece ball valve allows the main valve body to be separated from the valve bodies on both sides, enabling rapid online replacement and maintenance.
The working principle of the corrosion-resistant fluorine-lined ball valve is to unblock or block the valve by rotating the valve body. The valve body and the inner side of the valve body are all made of fluorine plastic. It has the characteristics of light switch, small size, reliable sealing, simple structure and easy maintenance. , wide range of use and other advantages.
