[DISCONTINUED] DA3+ Series - Double Seat Mixproof Valves
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
