Pneumatic butterfly valves are commonly used in industrial applications to control the flow of materials such as liquids, gases, and powders. These valves feature a disc-shaped closure element that pivots on a central axis and is operated by an actuator that utilizes compressed air or other gases to open or close the valve.

The performance of pneumatic butterfly valves can vary depending on a number of factors, including the type of actuator used, the size of the valve, the materials of construction, and the specific application in which the valve is used. VALCOFLOW pneumatic butterfly valves are good at:

1. Fast and accurate operation: Pneumatic butterfly valves can be operated quickly and precisely, making them ideal for applications that require frequent control of flow rates.

2. Low cost and easy maintenance: These valves are generally less expensive than other types of control valves, and they require relatively little maintenance when properly installed and maintained.

3. Wide range of materials and sizes: Pneumatic butterfly valves are available in a variety of materials and sizes to suit a wide range of applications, from small laboratory settings to large-scale industrial processes.

4. Good sealing performance: The disc-shaped closure element of a pneumatic butterfly valve can provide effective sealing when properly sized and installed, reducing the risk of leaks and contamination.

Overall, pneumatic butterfly valves can provide reliable and efficient control of material flow in a variety of industrial settings.
