If a problem occurs on a submarine whilst submerged a fast, secure surfacing of the boat is required and the on-board Emergency De-ballasting System EBS will be actuated. By actu-ating the EBS large amounts of air/gas will be transferred into the Main Ballast Tank (MBT) forcing the water out of the tank thus lowering the weight of the submarine and bringing it quickly to the surface.
Many navies across the world use SAB’s HP-AIR based Emergency Deballasting Systems on their ubmarines. We help them throughout development, build and trials with our expertise and our manpower.

In HP air driven EBS the main valves used are single stage slow opening blow valves, single stage fast opening regulators or two stage controlled blow valves. We supply different actuation valves according to customer’s request as well as all other required componrents oft he Emergency Blow System.
