Georg Schünemann GmbH is a leading valves design and manufacturing company producing a full range of on-board marine valves for all surface and subsurface military and commercial vessels. We are experts in the design and manufacture of high pressure valves, reducing stations, manifolds for air/gas applications up to 400 bar. The product range is complemented with seawater, hydraulic and bellow sealed valves and manifolds as well as complete systems.

Valves
High Pressure Valves
For many decades SAB high pressure valves are in use on submarines and surface ships worldwide. We put our focus on their quality, durability and service friendliness. Our broad product range has been developed in a modular design that offers opportunities for adapting to any customer specifications. Over the years SAB has developed from being a valve manufacturer to a partner of shipyards worldwide, helping to solve complex problems with our bespoke designs. All of our valves are pressure and function tested and fully meet the customers requirements. SAB realises that flow accuracy is imperative; consequently we will flow test our valves and manifolds.

See Water Valves
SAB`s seawater valves program cover the whole range required for submarines and surface ships. It includes globe valves, butterfly valves, sight glasses and filter for seawater applications up to DN300 and PN50 according to VG, BS – standards or customized products for submarines.


VALVES
Pressure Reducing Stations
Reducing stations are designed and built to satisfy our customers’ needs. They reduce HP air/gas to LP in a single monoblock housing with all flow paths integrated. All reducing stations can be equipped with integral filter, safety relief, stop, automatic stop, metering and gauge valves. A two stage reduction will provide a more stable outlet pressure even with rapidly decaying inlet pressure. Multi stage reducing station with one inlet and several outlet pressures available provides weight and space saving along with huge reduction in potential leakage paths.

Manifolds
SAB’s manifolds are 100% custom made according to the specifications. They can be equipped with any SAB standard or custom made cartridge valve and actuated manually, hydraulically, pneumatically or electronically to suit the functions needed. Monogas and/or gas mixtures can be filled with the multifunction valve (MFV).


VALVES
Systems
After many years of cooperation with navy shipyards and with a deep knowledge of ship’s systems SAB has begun decades ago to develop complete systems for navy ships. Based on the customer’s requirements we develop, build, test and service air control panels, emergency de-ballasting systems, built-in breathing systems, diesel start and turbine start systems.
