D4 Series - Double Seat Mix Proof Valves

Product Type:
Valves / Mix Proof Valves

Offers reliable separation of fluids and an ultra-hygienic option for enhanced cleanability.

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 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
DA4 2 Integrated upper and lower shaft seal and balancer flushing - Extensive cleaning of product contact surfaces
DA4 3 Metal orifices control CIP flow during seat lift - Reduces chemical and water loss consumption
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
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
8 Large separation cavity drain port - Less product risk and guards against pressure build up which could cause cross-contamination.
9 Flush 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
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.
