High-alloyed valves are designed for use with aggressive liquids

By Chemical Engineering | March 1, 2018

Alfa Laval

The UltraPure model (photo) from the Unique Mixproof valve product line is designed to meet the standards of biotechnology and pharmaceutical applications. Valves are packaged to ensure full traceability and are available in high-alloy materials, such as Hastelloy C22 and AL6XN. These alloys help to meet demands for corrosion resistance against aggressive media, including buffer solutions, cleaning liquids, high-salt solutions and more. Unique Mixproof valves are also suitable for use with hygienic products that contain high chloride concentrations or low pH levels. — Alfa Laval AB, Lund, Sweden
