D4 Series - Double Seat Mixproof Valves

FEATURES

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 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 such as one kit for 1.5" - 3.0" sizes
  • 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

 

Benefits:

 

Valve Type   Feature Benefit
D4 1 Radial seal design for reduced losses of product fluids during switching - Product cost savings

-Cleaner operating environment
Choice of seat lifting (SL) or non-seat lifting (NSL) actuator Modular design to fit a wide range of cleanability and functionality needs
Hazardous rated options available (ATEX Zone 1 or 2) Provides safe operation in critical applications
DA4 2 Integrated upper and lower shaft seal and balancer flushing -Extensive cleaning of product contact surfaces

-Helps to reduce external flush piping
3 Metal orficies control CIP flow during seat lift Reduces chemical and water loss consumption
Replacement insert fits into existing DA3+ housing Easy upgrade to next generation with improved features
D4 and DA4 4 Open yoke design -Reduces heat transfer from product zone into actuator

- Provides visual leak detection of damaged shaft seals

- Safety guard provided to reduce pinch points
5 Bolted flange connection for housing insert - Heavy-duty, secure connection

- Reliable and controlled assembly and disassembly of valve insert
6 Long ports to ease manifold building Helps to reduce spool pieces and welds to ease manifold building
Only two seal kit sizes used on entire range: DN40-DN65 (1.5" - 3.0") and DN80-DN100(4.0") Reduces inventory and maintenance costs
Fully integrated sensors to detect all critical positions - No external wires exposed to wash-down and mishandling

- Extra security to monitor seat positions during cleaning
No compressed air required for servicing Easy and efficient maintenance
7 Balanced 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
Reduced cleaning fluid losses to drain - Chemical and water savings

- Cleaner environment due to fewer chemicals and fluids spilling to the floor
8 Large separation cavity drain port Less product risk and prevention of pressure build-up that could cause cross-contamination
9 Flush cavity spray fixed connection (as standard) - Enhanced cleaning

- Removal of 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
Light overall weight Easier handling for maintenance
