CF Flange High Vacuum Angle Valves (Manual Drive): Overview, Features & Technical Parameters

The CF Flange High Vacuum Angle Valve is suitable for opening and closing pipelines in ultra-high vacuum systems and adopts a manual drive mode. It has the advantages of stable operation, reliable use, excellent sealing performance and long service life, making it one of the preferred valves for ultra-high vacuum equipment. The manual valve uses manual rotation of the handle as power to realize the opening and closing of the valve plate through threaded transmission; the direction of opening and closing is subject to the mark on the handle. The valve medium is air and a few corrosive gases.
