The pneumatic ball valve is simple to install and can adjust the height and level according to the actual needs. The frequency of the pneumatic ball valve is very low, but the isolation effect is very good, and the structure is tight, but the size and shape are not very large
This makes it easy to install, operate and reliable in use
Although the appearance is relatively small, the application life is not short
Application place of low-frequency ball valve Pneumatic ball valve Currently, three types of common plate type, polytetrafluoroethylene plate type and ball valve pneumatic ball valve are widely used in bridge engineering
The selection principle of main materials for bridge bearings is to basically select NR, CR, EPDM, IIR and chlorinated IIR under the premise of meeting engineering performance requirements and in combination with the requirements of environmental conditions
Multi purpose molding for bridge bearing manufacturing process
