Industrial Valves perform key functions in plants and pipelines and therefore have a considerable influence on customers‘ own processes: accuracy of control, reliability and safety are paramount.

Quality control at Mankenberg is thus acentral theme which runs through all aspects of the production process. At Mankenberg, quality control is a separate team whose members are directly answerable to the Managing Director. Everything that leaves our production halls has to be checked by the experienced hands of our quality control team.

But if we are honest, even these high standards are not enough to satisfy us when it comes to quality. All our suppliers are DIN EN 9001 certified and are subject to a strict evaluation system. It is included in the closed loop improvement process that we set up ourselves. When it comes to supplier relationships, feedback functions in both directions. This enables us to increase the degree of mutual transparencyand confidence.
