What Is a Flanged Pneumatic Butterfly Valve?

COVNA Pneumatic Flanged Butterfly Valves provide you with a reliable and flexible fluid control solution. It means a double flanged butterfly valve driven by a rack and pinion pneumatic actuator to open or close. Flanged butterfly valve can be customized into ANSI standard, DIN standard, JIS standard and GN standard according to your pipeline requirements. Furthermore, flanged butterfly valve can be customized into soft sealing butterfly valve or hard sealing butterfly valve to meet your various media needs.

Pneumatic actuator is a device that can help to achieve remote control. According to the pneumatic actuator type, it could be spring return type and double-acting type. Feature of spring return type including safe and when the air off, the valve will be close automatically. Features of double-acting type include responsive and high torque.

Features Of Flanged Pneumatic Butterfly Valve

● Offering the best solution for the large size pipeline which requires a flanged connection

● Available in cast iron and stainless steel 304/316/316L material for your choice

● Rack and pinion pneumatic valve actuator with high torque to fully open and fully close the valve

● Fast open and fast close

●What's more, it could be custom in metal seal to meet the high-temperature and high-pressure requirements
