The diaphragm inline valves provide reliable manual isolation across a wide range of vacuum applications. The robust diaphragm-sealed design completely isolates the operating mechanism from the vacuum environment, helping to ensure long service life and dependable performance.<\/p>\n\n\n\n

<\/p>\n\n\n\n

Available in ISO-KF sizes from DN10 to DN40, selected models feature a visual open-position indicator and integrated mounting options for easy system installation.<\/p>\n\n <\/div>\n <\/div>\n\t<\/div>\n<\/section>\n\n\n
