Possible Applications
The SPX FLOW SD and SDMS double seal mixproof valves are deployed in hygienic process lines where absolute separation of incompatible fluids is mandatory to prevent cross-contamination. They are primarily utilized in dairy processing plants, beverage bottling lines, breweries, and pharmaceutical manufacturing systems where CIP cleaning agents must flow simultaneously through one valve housing while product passes securely through the adjacent pipeline. Typical integration points include tank outlet assemblies, complex manifolds, and pasteurization skid switchover nodes where dual-seal technology ensures that any potential leakage is safely diverted to atmosphere rather than breaching the product boundary.
