Pneumatic Actuated Butterfly Valve

Pneumatic actuated butterfly valve is the butterfly valve equipped with pneumatic actuators. Its valve disc is driven to rotate within a 90-degree range and powered by the pneumatic actuator. According to different ways of action, pneumatic actuated butterfly valves can be classified into switch-type and intelligent regulation-type. Specifically, the switch-type pneumatic actuated butterfly valve allows for full opening or closing of the valve, while the intelligent regulation-type is possible to add a valve positioner to the actuator to input corresponding signals, enabling arbitrary adjustment of the butterfly valve disc from 0 to 90 degrees.

The pneumatic actuated butterfly valve is highly useful for controlling highly flammable liquids such as petrochemical products, oil, and natural gas. It works through pneumatic mechanisms, enabling rapid functionality while remaining immune to fire and electrical short circuits. As a result, it is considered the most cost-effective and energy-efficient industrial valve.

We provide switching mode two-position types and intelligent regulating types. If you want to get more information, please contact us !
