High-Performance Pneumatic Butterfly Valves for Industrial Flow Control

A pneumatic butterfly valve is a flow control device that uses a pneumatic actuator to operate a butterfly valve, commonly used in pipelines for regulating air, gas, water, and other media. These valves feature a circular disc mounted on a rotating shaft, allowing for quick shutoff and throttling.
Pneumatic actuated butterfly valves are available in double acting and spring return types. In a spring return configuration, the actuator uses compressed air to open the valve and a spring to close it, while double acting actuators use air to both open and close the valve.
Constructed from materials such as ductile iron for the valve body and anodized aluminum for the actuator, pneumatic butterfly valves offer strength, corrosion resistance, and long service life, making them ideal for industrial automation and process control systems.
