Our History

The story of Stafsjö begins in 1666 when Gerdt Störning founded Stafsjö Bruk. What started with the manufacturing of cannons continued for nearly 200 years and laid the foundation for a strong engineering tradition.

In 1928, the first knife gate valves were introduced and manufactured, marking the beginning of a new industrial focus that continues to define the company today.

Now, 360 years after it all began, this legacy of engineering expertise and steady innovation continues to evolve, driving the development of technologies and solutions that will carry the company into the next century and beyond.
