DA3_D4_Insert_Upgrade_Graphic_200x400 The next generation of mix proof valve technology is the result of continued development from both APV™ and Waukesha Cherry-Burrell™ process technologies. Used for the reliable separation of dissimilar fluids, the D4 Series helps fulfill today’s customer demands for production flexibility, increased productivity, rapid return on investment (ROI), and improved product quality across the Food & Beverage, Dairy, Personal Care and Brewing process industries.


High value, Low life cycle costs:
  • Tiered model range helps to increase ROI and align with customer budgets
  • “All In” standard features provide exceptional value
  • Reduced inventory costs with same seal kit used on multiple size ranges: DN40-DN65 (1.5”-3.0”) and DN80-DN100 (4.0”)
  • Reduced CIP losses improve cost savings
  • Low air consumption and air supply requirements
  • Long housing ports ease manifold building
  • Integrated shaft seal flush reduces need for external piping
  • Replacement insert available to easily upgrade existing installations

Reliable performance:
  • Fully balanced design helps to prevent hydraulic blocking, withstand pressure spikes, and enables flexible flow direction without slamming
  • Light overall weight helps support handling without lifting tools
  • Slim stainless actuator is fully enclosed to prevent fluid ingress
  • Range of control units and bus communication for automated operation
  • No compressed air needed for removal and servicing

Cleanability:
  • Designed to the latest hygienic standards
  • Standard cavity spray cleaning
  • Extensive cleaning of product contact seals

  • Safety guard provided to reduce pinch points
 5Bolted flange connection for housing/insert
  • Heavy duty, secure connection
  • Reliable and controlled assembly and disassembly of valve insert
 6Long ports to ease manifold buildingHelps to reduce spool pieces and welds to ease manifold building
 7Balanced upper and lower shafts (as standard)
  • No hydraulic blocking
  • Resistant against pressure spikes
  • Flexibility in either flow direction through the valve (top-to-bottom or bottom-to-top) without water hammering
 8Large separation cavity drain portLess product risk and guards against pressure build up which could cause cross-contamination.
 9Flush cavity spray fixed connection (as standard)
  • Enhanced cleaning
  • Removes residual media in separation cavity when full CIP is not readily available
  • Hard-piped flush can be used without need to be removed during valve maintenance

Double seat mix proof valves are used to efficiently process two different fluids (typically product and CIP) through the valve simultaneously. The mix proof design has two seats which isolate the upper and lower pipe lines when the valve is in the fail-safe closed position. The atmospheric vent cavity in between the seats creates a path for any leakage should the seals fail as well as a drain for CIP solution during seat cleaning. An external CIP spray flush is included to provide enhanced cleaning of the leakage and vent cavity while the valve is closed or open during production.
