Starting in 1920 only as a department in the toy factory, Margarete Steiff GmbH, in swabian Giengen (Brenz), the ALLIGATOR Ventilgruppe has developed into a worldwide leading specialist for air valves. The original merits of the founder – farsighted trading, quality awareness, attention to detail and above all, clever inventive talent, are today, 90 years later, still the key to the Group's success. The great inventor in the Steiff family, Richard Steiff, would surely be proud of our latest developments, whether tire pressure retaining valves as safety components in luxury-class vehicles, components for Tire Pressure Monitoring Systems (TPMS), special tire mold valves for the production of tires or all the special solutions for our customers in general engineering.
