Cargo valves

Cargo valves

The butterfly valve is a perfect choice for the shipping and shipbuilding. Thanks to its massive stainless-steel seat it is very suitable as cargo valves.


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.
