[DISCONTINUED] DA3+ Series - Double Seat Mixproof Valves
Because of necessary upgrades and constant innovation to create the most efficient and sustainable valves possible, SPX FLOW no longer offers the APV DA3+ Series of valves as new equipment. But since there are DA3+ valves in operation around the world, the NEW DA4 valve insert can be installed in the OLD DA3+ housing. This is a simple process, and you will have the latest valve technology without making major modifications to your plant. Upgrading typically takes less than 5 minutes.
