Quality is a top priority at A. u. K. Mueller. Every valve and every component that leaves our factory is subjected to a 100% inspection. We ensure that our valves meet the highest quality standards right from the design and layout stage. Our components and products are also subject to a constant monitoring process during the manufacturing process.

In our laboratory, we have numerous test rigs available for this purpose, including creep tests, burst pressure tests or for testing the flow behaviour of our products and those of our customers.

As a special service, we offer our customers the measurement and testing of their final product with a view to certification in accordance with the relevant standards. One example is the pressure surge test in accordance with EN 15091 for your faucets. In this way, we support you in optimising your products.
