The name A. u. K. Mueller is associated with more than 70 years experience in the development and production of electric solenoid valves, control units and special fittings which symbolizes reliability and quality. Therefore, the objective of our quality policy is reliability, durability, safety and usability of our products to ensure optimal cost.

Quality management is integrated into each project process from the very beginning. We create security during the development phase of a product by the use of modern flow and electromagnetic simulation tools as well as rapid prototyping. All components are carefully tested during the production process by test rigs which are developed and manufactured by ourselves. A comprehensive quality management system according to ISO 9001 confirms our quality.

Quality Management System according to EN ISO 9001:2015
The official certification of our quality management system according to EN ISO 9001 has been achieved in October 2001. Since then we continuosly have improved our internal standards and the derived goals of our quality politics. Successful recertifications confirm our strategy and strengthen the confidence of our partners into our company.

International standards are subject to continuous change. It is vital to monitor the relevant standards to ensure that their requirements are incorporated into the design of our products.

Test parameters and procedures are also effected, with our development and production testing being constantly updated to reflect the latest methods. Often our duration testing will use more extreme conditions or extend beyond the criteria set by the standards. Customer specific tests can also be included.

[Translate to English:] DIN Deutsches Institut für Normung

DIN Deutsches Institut für Normung (German Institute for Standardization)

DIN is a standard conformity mark which documents the compliance of a product with the requirements of the relevant DIN standard. But the DIN does not only develop standards for Germany, but also plays a role  in working on international standards (CEN) as well (for example, the EN standards).

The standardization work serves as a unification of material objectives, taking into account the particular state of science and technology. For this purpose working groups are in place, equipped with various diverse expertise, which provide essential work for the development of existing standards or to create new ones.

We actively contribute in the DIN and are involved in the development of relevant standards , and we provide our own practical know-how of applications and products.
