Next Generation Mixproof Valve Technology: ³Ô¹ÏȺ D4 Series

Advanced Fluid Separation for Process Industries

The next generation of mixproof 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.

Value and Efficiency

High Value with Low Lifecycle 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

Optimized Operation and Control

• Reduced chemical and cleaning fluid losses
• Large separation cavity drain port prevents cross-contamination
• Flush cavity spray connection for enhanced cleaning
• Lightweight valve body for easier handling

Actuator Warranty & Reliability

The actuator supplied with this valve is covered by a 5-year actuator warranty, or up to 1 million actuations, whichever comes first. Built with fully welded, sealed, maintenance-free construction, it eliminates internal servicing and reduces wear components to deliver long-term durability in demanding hygienic processing environments.

Key benefits include:

• Maintenance-free operation with no internal servicing
• Fewer spare parts and improved total cost of ownership
• uptime and production continuity
