Pneumatic butterfly valve is a kind of regulating valve widely used in industrial pipelines. Its core component is a disc-shaped disc that is mounted in a pipe and rotates on its axis. When the disc rotates 90 degrees, the valve closes; When rotated 0 degrees, the valve opens.

The working principle of the pneumatic stainless steel butterfly valve is to control the rotation of the butterfly plate through the pneumatic actuator. The pneumatic actuator receives compressed air as a power source, and drives the butterfly plate to open or close according to the requirements of the control signal. This driving mode makes the pneumatic butterfly valve have the advantages of fast response speed, high control accuracy, simple operation and so on.

Pneumatic butterfly valves are widely used in industrial fields. It is mainly used to adjust the flow rate and pressure of the medium, as well as to achieve the cutting and connecting of the pipeline. Because of its simple structure, small size and light weight, the pneumatic eccentric butterfly valve has good flow performance in the pipeline system, which can reduce fluid resistance and energy consumption. In addition, the pneumatic 4 Inch butterfly valve also has good corrosion resistance and high temperature resistance, and can adapt to various harsh environments.

Pneumatic butterfly valves are used in many industrial fields, such as petrochemical, electric power, metallurgy, pharmaceutical, food and so on. In the petrochemical industry, pneumatic butterfly valves are often used in the pipeline system of crude oil, refined oil, chemical raw materials and other media. In the power industry, pneumatic butterfly valves are mainly used in the transmission pipelines of cooling water, fuel gas and other media in power plants. In the metallurgical industry, pneumatic butterfly valves are used in piping systems with high temperature molten metals and other media.

In short, the pneumatic butterfly valve plays an important role in the industrial pipeline system with its unique structure and working principle. It can not only achieve accurate control of medium flow and pressure, but also has good corrosion resistance and high temperature resistance, so it is widely used in various industrial fields.
