Product Overview

The pneumatic on-off butterfly valve, also called pneumatic shut-off butterfly valve, is mainly used for two-position medium shut-off control in industrial pipelines. It uses air pressure to drive the butterfly disc to achieve full opening and full closing actions.

According to different working modes, the valve is available in normally open and normally closed types. When encountering air loss, power failure or pneumatic circuit failure, the valve can automatically reset to its preset open or closed state to ensure pipeline safety.

With ultra-fast opening and closing speed, this valve is highly suitable for working conditions requiring rapid switching and emergency shut-off.
