[DISCONTINUED] DA3+ Series - Double Seat Mixproof Valves

Product Type(s) : Mixproof Valves
Description :

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.

WHERE TO BUY

Upgrade from APV DA3+ to DA4 Mixproof Valves

Simplified Valve Technology Transition

Due to continuous innovation, SPX FLOW has discontinued new production of the APV DA3+ Series. However, the DA4 valve insert is fully compatible with existing DA3+ housings, offering an easy upgrade path to the latest valve technology—typically in less than 5 minutes with no major plant modifications.

Enhanced Performance for Modern Process Demands

The DA4 Series delivers reliable fluid separation and meets today's requirements for greater production flexibility, efficiency, ROI, and product quality across industries such as:

  • Food & Beverage
  • Dairy
  • Personal Care
  • Brewing

Benefits of Upgrading to DA4

Key Improvements

  • Integrated position feedback
  • Enhanced seal design for extended lifespan
  • Open yoke for visual leak detection and reduced heat transfer
  • Fully welded actuator to prevent corrosion
  • Low air supply requirement for efficient actuation
  • Slim actuator profile for easier installation and maintenance

Support for DA3+ Installations

Servicing Legacy Equipment

If you're not ready to upgrade, DA3+ spare parts are still available to minimize downtime. Please note: OEM parts are required to maintain warranty coverage on DA3+ valves.

Explore Your Options

Whether you’re ready to move forward with DA4 or maintain existing equipment, SPX FLOW provides the solutions you need. Explore the DA4 Series. Get genuine spare parts for DA3+ valves.
