Hygienic Double Seat Mixproof Valve 3A, 316L Stainless Steel

SY-DSMV

Sangyie Hygienic double seat mixproof valves are designed to handle flow of two different media synchronously without risk of cross-contamination. Hygienic double seat mixproof valves offer a safe separation of media and prevents accidental mixing in case of valve seat failure. The most usual applications are the ones that require safe separation of the product and CIP (Cleaning-in-Place) and SIP (Sterilization-in-Place) solutions in a single point or at the end of a manifold, widely used in heat exchanger, AI liquid cooling systems, food-processing, beverages, brewing, wine, dairy, cosmetic, personal care, pharmaceutical, biotechnology and semiconductor industries.
