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

The KF Flange High Vacuum Angle Valve adopts a manual drive mode. It features reasonable structural design, aesthetic appearance, stable operation, small volume, reliable use, good sealing performance and long service life, making it one of the preferred valves for vacuum equipment. The valve takes manual rotation of the handle as power, which is connected to the valve plate through a mechanism and drives the valve plate to open and close. The valve medium is non-corrosive gas.
