The Pneumatic Vacuum Butterfly Valve is a high-performance valve specially designed for vacuum systems, gas control applications, and automated pipeline operations. It combines the compact structure and reliable sealing performance of a butterfly valve with the fast response and remote control capability of a pneumatic actuator.

Designed for vacuum, negative pressure, and low-pressure gas systems, this valve provides excellent air tightness, stable operation, and long service life. The pneumatic drive system enables rapid opening and closing, making it suitable for automated production lines and process systems requiring frequent operation.

The valve is widely used in vacuum equipment, semiconductor manufacturing, chemical processing, pharmaceutical systems, food processing, HVAC, and industrial automation applications.
