Karl Adams pursued a unique concept with his idea of a highly versatile valve. Particularly in the case of metallic seals, it was to set new standards in terms of tightness, service life and range of uses. The resourceful company founder was able to implement this idea by means of gradually improving on the original valve technology to arrive at the triple-eccentric sealing system. The current technology enables the valve to move into its nal sealing position without friction.

Innovations: investments in the future

Throughout the 50-year development of the company, one principle has always remained: the ingenuity
with which Karl Adams started the company. Only a few years after registering its rst patent, the company patented further innovations, such as the metallic seal for valves. The following years saw the constant de- velopment of new products and the enhancement of details that led to a great number of additional patents. This innovative power was constantly underpinned by far-sighted investment decisions in state-of-the-art research and production methods.
