Somas Instrument AB

Somas Instrument AB is a Swedish engineering company specializing in the development and manufacture of high-grade stainless steel control and on/off valves. Headquartered in Säffle, Värmland, the family-owned enterprise has evolved from a local mechanical workshop into a globally recognized supplier of flow control solutions. While its roots lie in the pulp and paper industry, the company has established a significant footprint in the maritime and offshore sectors, providing critical components for commercial vessels, chemical tankers, and marine engine systems. Founded in 1945, the company originally operated under the name "Sliperi Och Mekaniska Arbeten Säffle," from which the acronym "Somas" is derived. Initially focused on grinding and polishing cutlery, the business pivoted in the late 1940s to meet the growing demand for industrial valves. This historical expertise in metalworking laid the foundation for its modern production capabilities, which remain centered in Sweden. Today, the company controls its entire value chain, from research and development to precision manufacturing, ensuring that its products meet the rigorous standards required by heavy industries. In the maritime domain, Somas Instrument AB plays a vital role in ensuring the safety and efficiency of liquid cargo handling. Its triple-eccentric butterfly valves and ball segment valves are widely utilized on product and chemical tankers, where absolute tightness and material integrity are essential to prevent cross-contamination of cargoes. The company’s valves are engineered to withstand the corrosive nature of marine environments and the high flow rates associated with loading and unloading operations. Beyond cargo handling, the company is deeply involved in marine engine efficiency and environmental compliance. With the shipping industry facing stricter emissions regulations, Somas provides specialized exhaust gas valves used in aftertreatment systems, including Selective Catalytic Reduction (SCR) and Exhaust Gas Recirculation (EGR) units. These components are designed to endure extreme temperature cycles and vibrations, helping vessel operators manage exhaust flows and recover waste heat. To support these critical systems worldwide, the company maintains a broad network of service partners, recently expanding its global reach to ensure 24/7 support for marine installations. Through its focus on durability and precision, Somas Instrument AB serves as a key technical partner for shipbuilders and operators aiming to optimize performance and sustainability at sea.
