GU series manual vacuum ball valve is in 1.3×10-7~6×105Pa vacuum system used to open or block the flow of the valve, widely used in all kinds of gas, liquid and other positive and negative pressure pipeline system, in line with GMP standards.
Structural characteristics
1. Small switching torque, stable and reliable operation;
2. Compact structure, light weight, simple appearance and beautiful appearance;
3. The valve can be used under both high vacuum and positive pressure;
4. Unique sealing structure design, leakage rate can reach < 1×10-10Pa.M3/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.
