1. The switching torque is small, and the work is stable and reliable;
2. Compact structure, light weight, simple and beautiful appearance;
3. The valve can be used both for high vacuum and under certain positive pressure;
4. The sealing structure design is unique, and the leakage rate can reach <1×10*Pa.M/S;
5. Because the ball valve is fully conductive and can meet the requirements of ultra-high vacuum, it can also be applied to the accelerator vacuum system.
