Stainless Steel Double Disc Wafer Type Non-Return Valve Zero-Leakage Backflow Prevention (2)

Key Technical Advantages:

1. Double Disc Design for Rapid Response

Dual Spring-Assisted Discs: Close instantly upon flow reversal, preventing water hammer and minimizing pressure surge.
Low Cracking Pressure: Opens at 0.5 psi, reducing energy loss and ensuring efficient flow.

2. Full 316L Stainless Steel Construction

Corrosion Resistance: Withstands corrosive fluids, including chlorinated water, mild acids, and alkalis.
Durability: Excellent mechanical strength for pressures up to **PN16** and temperatures from -29°C to 200°C.

3. Wafer-Type Compact Design

Space and Weight Savings: 50% lighter and more compact than swing check valves, simplifying installation in tight spaces.
ANSI/DIN Flange Compatibility: Fits between standard flanges without additional hardware.

4. Zero Leakage and Silent Operation

Bubble-Tight Sealing: Achieves API 598 leakage standards for reliable backflow prevention.
Noise Reduction: Spring-assisted disc closure eliminates valve slam and operational noise.

5. Low Maintenance and Long Service Life

No Lubrication Required: Self-cleaning discs reduce wear and extend service life.
Easy Inspection: Modular design allows for quick maintenance without removing the valve from the pipeline.
