These are used to avoid any fluid back flow. SAB’s non return valves are 100% tight in sealing. They can be supplied in an angle pattern, inline design or as cartridge Screw Down Non Return valves and Open/ Non-Return/ Close valves for highest demands on tightness and safety.

SAB filters protect all downstream equipment against all kind of solid contamination down to filter fineness of 10 micron. The casing can be equipped with a drainage screw/ venting screw. SAB produces a standard range of single cartridge filters but have developed a bi-directional model which filters the flow in two directions.

All SAB hull valves utilise the cartridge valve design, they can be operated manually or with electrical or hydraulic actuators. They work on the “Kingston” principle to include a non-return function in case of breakage of the valves internals. The unique design of the SAB double hull valves gives a failsafe solution integrating two shut off valves in one housing. All SAB hull valves can be equipped with Stop, Non-Return, Screw down Non-Return or Open-Close-Non-Return valve inserts, electronic stroke indicators, locking devices and control-switches for remote or local operation and can be actuated manually, electrically and hydraulically.

SAB safety valves are type tested and CE certified to PED2014/68/EU. They are built as proportional or fast acting valves. The SAB supply is full factory inspected and preset to the system requirement, with 3rd party inspection if customer requests. SAB works together with all certified bodies and 3rd parties who include the TUV, GL, and LR to ensure they fulfill the customer’s requirements.
