The pneumatic flange ball valve
The pneumatic flange ball valve can be tightly closed with 90° rotation operation with air and a very small driving torque. The ball valve has main features including compact structure, simple operation and maintenance. It is applicable to general working media such as water, solvent, acid and natural gas as well as media under serious working conditions such as oxygen, hydrogen peroxide, methane and ethylene.
