Floating ball valves are divided into ordinary carbon steel series (WCB&A105) based on shell materials according to different service requirements. Stainless steel series 304,316; Low temperature steel series LCB,LCC; Anti - sulfur series, etc.
Stainless steel floating ball valves are suitable for general industrial use.
Stainless steel floating ball valve is mainly characterized by the ball without supporting shaft, the ball is held by two seats in a "floating" state, it is mainly used in the pipeline to cut off, distribute and change the direction of media flow. Floating ball valve main characteristics of the valve seat seal design, reliable reverse seal valve stem, fireproof static function, automatic pressure relief and lock device structure characteristics.
Suitable for: chemical, petroleum, natural gas, metallurgy and other industries and hydrogen sulfide containing media, impurity, serious corrosion of natural gas pipeline.
The main structural features of floating ball valves are:
1. The valve is provided with open and close position indication;
2. Unique seat sealing structure;
3. Stem anti-flying structure;
4. Fireproof structure;
5. Anti-static device;
6. Locking device; 7. No leakage structure of middle flange (connection between valve body and left body).
