Cargo valves


The butterfly valve is the perfect choice for the shipping and shipbuilding industries. Thanks to its massive stainless steel seat it is very suitable as a cargo valve. Properties such as low total weight, short “face to face”, ease of use and most importantly, good tightness makes this valve an excellent choice for marine applications.


The butterfly valve is useful for handling liquids. The metallic seat is not affected by a high velocity flow. Therefore the valve maintains its tightness even after many years of use. Butterfly valves are the most common type of cargo valves.

Product and chemical-tankers in the shipping/shipbuilding industry use SOMAS butterfly valves in their pipelines in order to separate different cargos from each other during transport.
Ball valves are delivered for leakage control purposes.


SOMAS butterfly valves offer several different functions specifically designed for the shipping and shipbuilding field.

  • Dimensions: DN80-DN400
