Analysis and Research on the Ball of Fixed Pneumatic Ball Valve The fixed pneumatic ball valve is characterized by small switching torque, fast switching, small flow resistance coefficient, fire prevention, anti-static, automatic valve body discharge, etc. It is especially suitable for high pressure, high temperature and large diameter pipelines, and is widely used in various fields of production and life such as natural gas, oil products, chemical industry, metallurgy, urban construction, environmental protection, etc. The fixed pneumatic ball valve consists of valve seat, pneumatic ball valve, upper and lower valve stems, valve body and other parts

In view of such structure of the pneumatic ball valve, the installation of the pneumatic ball valve also has some characteristics. Here we take the pneumatic pipeline ball valve as an example:
1. Any section of the pneumatic pipeline ball valve can be installed at the upstream end, and the handle ball valve can be installed at any position of the pipeline. If the ball valve is equipped with a pneumatic actuator, it must be installed vertically, and the inlet and outlet of the valve are in a horizontal position.
2. The sealing gasket shall be installed between the pneumatic pipeline ball valve flange and the pipeline flange according to the pipeline design requirements.
3. The bolts on the flange shall be tightened symmetrically, step by step and evenly.
4. If the pneumatic pipeline ball valve adopts pneumatic, electric and other actuators, the installation of air source and power supply shall be completed according to the instructions.
