High Sealing performance Aluminum Bronze Dual Plate Check Valve

Product Features:

Crafted from aluminum bronze alloy (C95400/C95800), the valve body and plates withstand aggressive media, saltwater corrosion, and cavitation. The dual-disc design ensures rapid closure, eliminating water hammer and preventing dangerous backflow. Unique nitrile rubber (NBR) or EPDM seals bonded to aluminum bronze plates deliver Class VI sealing (per EN 12266-1), exceeding industry standards for leak-tight performance.

Key Advantages:

1. Zero-Leakage Guarantee: Dual-sealing surfaces + spring-assisted closure achieve bubble-tight shutoff (tested to 1.1x PN).  

2. Ultra-Low Pressure Drop: Slim-profile design reduces flow resistance by 40% vs. swing check valves.  

3. Maintenance-Free Operation: Self-cleaning plates and corrosion-proof materials ensure 10+ year service life.  

4. Universal Installation: Horizontal/Vertical (flow-upward) mounting flexibility.  

5. Certified Safety: Compliant with CE PED 2014/68/EU, UKCA, WRAS, and ACS standards.
