Ergomatic VBS vacuum relief valves are designed for vent-from-atmosphere applications in the installation of ballast water treatment systems on ships. The VBS series utilizes a spring loaded diaphragm, typically adjusted for -0.2bar vacuum pressure, providing reliable and consistent relief of potential vacuum pressure build-up in ballast piping, often caused by excessive fall height, in pump room or deckhouse BWTS installations.
