SPX APV D4 / DA4
Used for the reliable separation of dissimilar fluids, the D4 Series helps fulfil today’s customer demands for production flexibility, increased productivity, rapid return on investment (ROI) and improved product quality in the Food & Drink, Dairy, Personal Care and Brewing process industries.
The D4 Series model range includes:
- D4 – primary, price-competitive model, which meets basic mix-proof needs for reliable separation, seat lift (SL) or non-seat lift (NSL) cleanability, and low product switching losses
- DA4 – ultra-hygienic model for critical applications requiring enhanced cleanability of product contact surfaces and low CIP losses to drain.
Features and benefits:
- Tiered model range helps to increase ROI and meet 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 process two different fluids efficiently (typically product and CIP) through the valve simultaneously. The mix-proof design has two seats that isolate the upper and lower pipe lines when the valve is in the fail-safe closed position. The atmospheric vent cavity between the seats creates a path for any leaks, 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.
