Our History

The story of Stafsjö begins already in 1666 when Gerdt Störning founded Stafsjö Bruk. It started with manufacturing of cannons, which lasted for almost 200 years. In 1928 the first knife gate valves were introduced and manfuctured by Stafsjö. This is the legacy and technology we will continue to push and bring into next century.
