Our control valves also play an important role in the extraction of metals. Where mechanical separation processes no longer suffice, the metal is leached with the help of chemicals. To do so, ground ore is mixed with different liquids. Usually, the created slurries are highly abrasive and corrosive. Controling them requires equipment that functions reliably even under the most adverse conditions and requires minimum maintenance.

Many of our products are used in these applications. They not only withstand corrosive solutions and the strong abrasion, they are also resistant to the heavy vibration found at many places in the huge plants. In addition, the valves fulfil ecologically relevant control tasks in recovering and treating the water used. Innovative valve accessories, such as our smart SAMSON positioners for integral attachment, ensure the safe exchange of data in the process and allow for predictive maintenance.
