How to choose the right electric ball valve

According to reports, in the next 10 years, my country will have more than 20000 kilometers of oil pipelines to be built, including transnational oil pipelines such as Russia and Kazakhstan. In addition, after the "West-East Gas Pipeline", my country will build more than 20000 kilometers of transnational gas pipelines and branch lines.

Working principle and advantages of pneumatic ball valve

Pneumatic ball valve is a valve that controls the valve core switch through a pneumatic device. Its working principle is mainly to apply pressure to the pneumatic device through the air source, so that the valve core rotates in the valve body, thereby realizing the opening and closing of the valve. Pneumatic ball valve is mainly composed of valve body, valve core, pneumatic device and connecting pipeline and other components.
