Unique Mixproof valves

Unique Mixproof family of double seat valves



Application Double seat valves handle the simultaneous flow of two different products or fluids through the same valve at critical pipeline junctions, eliminating the risk of cross-contamination.
The double seats forms a leakage chamber between them under atmospheric pressure during every working condition. In case of rare accidental leaking of product, this will flow into the leakage chamber and be discharged through the leakage outlet.Benefits Maximum product safety, minimized risk of cross-contamination Enhanced product yield due to cost-effective, spillage-free operation Optimized plant efficiency and enhanced cleanability More uptime due to spillage-free design with double lip seal, built-in leakage detection and leakage chamber Fully configurable with a broad range of models and options to meet virtually any hygienic processing requirement


From 2023 the family is extended with: Unique Mixproof Process a compact version of our double seat mixproof valves. Predefined and available in a range of sizes that meet your fundamental hygienic processing requirements Unique Mixproof CIP a lightweight double seat mixproof valve, for efficient and safe CIP flow management in hygienic applications.
