NKQ41F-16-100C,P.R

The product description

GU series manual vacuum ball valve type is used to open or cut off air flow in 1.3* 10-7-6 * 105PA vacuum system, widely used in all kinds of gas, liquid and other positive and negative pressure pipeline system, in line with GMP standards.

Working principle:

The valve stem drives the valve ball to turn 90° to achieve the purpose of switching

Product features

1. Switching torque is small, stable and reliable.

2. Compact structure, light weight, simple appearance, beautiful

3. The valve can be used not only in high vacuum, but also under certain positive pressure

4. The sealing structure is unique and the leakage rate can be up to panel 1*10-10 PAM3 /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.
