The Electric Vacuum Butterfly Valve is an automated flow control device designed for vacuum systems, utilizing an electric actuator to drive the butterfly disc for rapid switching or precise regulation. It features corrosion-resistant materials (e.g., stainless steel, PTFE seals), zero-leakage sealing, and compatibility with high-vacuum environments, making it ideal for applications in semiconductor manufacturing, pharmaceuticals, food processing, and chemical industries where sterile or vacuum-secured operations are critical.
