Overview and application of pneumatic expansion butterfly valves

2024/03/19

The working principle of pneumatic expansion butterfly valve is to rely on compressed air provided by the air source to cause elastic deformation of the sealing pair inside the valve body, thereby achieving switch control. After the gas source enters the valve body, it is compressed to a certain pressure through a compressor and then sent into the cylinder, causing the piston to move left or right, thereby pushing the butterfly plate to open or close the valve.

Pneumatic expansion butterfly valve mainly consists of valve body, butterfly plate, pneumatic actuator and other parts. When the pneumatic actuator receives a control signal, it will drive the butterfly plate to move inside the valve body, thereby achieving the opening and closing of the valve. The action of the pneumatic actuator is controlled by compressed air, and the air pressure and flow can be adjusted according to the needs to achieve precise control of the valve.

Application of pneumatic expansion butterfly valves in industry:

Pneumatic expansion butterfly valves are widely used in various industrial production processes, such as chemical, petroleum, power, food and other industries. It can be used to control various fluids, such as liquids, gases, slurries, etc. In practical applications, different specifications and materials of valves can be selected according to specific process requirements to meet different control requirements.
