than 150 years ago the history of the production of industrial
fittings in Germany began in Magdeburg. From tradition and historic
findings we know that for example Romans and Egyptians already several
thousand years ago used fittings made of bronze-alloy, which were
similar to our gate valves and clack valves
development and production of high-capacity industrial fittings
became necessary after the invention of the steam engine and the
resulting roaring technical development in Europe.
