In 1921, Rolf Nobel, nephew of famous chemist and inventor Alfred Nobel, laid
the foundations for what is now Durgo. From day one we have always strived to
be the reliable link. We stand with one foot firmly rooted in our Swedish craftsmanship
tradition, the one that brought us to where we are, and the other foot
in modern technology. This secures the levels of quality and safety demanded
of us.


Rolf Nobel, nephew of the well-known Alfred Nobel, founds AB Durgo in Hagalund, just north of Stockholm.


Erik Andersson takes over Durgo. Even today, the company is run within the family. The flush valve boosts business with the entrance of water toilets in Sweden. Our first safety valve is developed.
