Features

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 todays 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

Theory of Operation

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.
