A pneumatic butterfly valve is a type of butterfly valve that is operated by a pneumatic actuator. The actuator uses compressed air to drive the valve disc and control the flow of fluid through the pipeline.

Pneumatic butterfly valves are commonly used in applications where precise control of the flow rate is required, such as in chemical processing plants, water treatment plants, and HVAC systems. They are also used in applications where frequent valve operation is required or where manual operation is impractical.

Pneumatic butterfly valves are available in a range of sizes and materials, including stainless steel, carbon steel, and ductile iron. They can be designed for use in a wide range of operating temperatures and pressures, depending on the specific application requirements.

When selecting a pneumatic butterfly valve, it’s important to consider the specific requirements of your application, including the valve size, pressure rating, and temperature range. It’s also important to choose a reputable manufacturer that provides high-quality products and reliable technical support.

In addition, the selection of the pneumatic actuator should also be considered. The actuator should be chosen based on the required torque or force required for the valve operation, and the type of control signal required, such as on/off, modulating, or proportional control.

Overall, pneumatic butterfly valves are a reliable and efficient solution for controlling the flow of fluid in a wide range of applications.
