Thanks to its exceptional resistance to seawater corrosion, high mechanical strength, and anti-biofouling properties, our Aluminum Bronze Wafer Check Valve is a premier choice for demanding applications. Below are key industries where its performance excels.
Our robust aluminum bronze Wafer Type Non Return Valve offers unparalleled resistance to saltwater corrosion and biofouling, making it the ideal solution for ballast systems, seawater cooling circuits, and fire suppression lines on commercial vessels and naval ships.
In reverse osmosis (RO) and multi-stage flash (MSF) desalination, our Wafer Type Non Return Valve is essential for preventing backflow in high-salinity brine and corrosive seawater intake lines, ensuring process integrity and long service life.
Engineered for harsh offshore platforms, this aluminum bronze Wafer Type Non Return Valve provides reliable, maintenance-free performance in seawater cooling loops, firewater systems, and utility lines, withstanding constant exposure to corrosive salt spray and marine environments.
For handling corrosive media such as chlorinated water, sulfuric acid, and other aggressive chemicals, our Wafer Type Non Return Valve provides a superior, cost-effective alternative to exotic alloys, preventing process contamination from backflow.
Coastal power plants rely on consistent seawater cooling. This Wafer Type Non Return Valve protects critical pumps and condensers from back-siphonage, ensuring operational uptime with its excellent resistance to erosion and corrosion from brackish water.
In mining, where abrasive slurries and corrosive mine water are common, our heavy-duty aluminum bronze Wafer Type Non Return Valve excels, providing superior wear resistance and preventing system contamination from reverse flow in dewatering and processing lines.
For large-scale HVAC and chiller systems, especially in coastal regions with salt-laden air, this Wafer Type Non Return Valve prevents backflow in condenser water lines, offering extended service life and preventing premature failure due to corrosion.
The non-sparking properties and excellent performance at low temperatures make our aluminum bronze Wafer Type Non Return Valve a safe and reliable choice for utility and firewater systems within LNG facilities and on carriers, ensuring utmost safety.
This Wafer Type Non Return Valve is perfectly suited for the pulp and paper industry, effectively resisting corrosive bleaching agents and acidic process water to ensure uninterrupted production flow and protect upstream equipment from damaging backflow.
Ready to configure for your project?
Aluminum Bronze (like C95800) offers an exceptional combination of high strength and superior resistance to seawater corrosion, pitting, and biofouling (marine growth). It significantly outperforms standard stainless steels in these environments and serves as a cost-effective, high-performance alternative to more exotic alloys.
This valve excels in Marine & Shipbuilding, Desalination Plants, Offshore Oil & Gas Platforms, and Coastal Power Generation. It is designed for handling media such as seawater, brackish water, brine, and certain industrial chemicals where standard materials would quickly fail.
Absolutely. It possesses high mechanical strength and excellent wear and abrasion resistance, making it suitable for water with suspended sand or silt. Furthermore, it is a non-sparking material, which is a critical safety feature for applications in LNG facilities or offshore platforms.
To prevent galvanic corrosion, the internal components should be of a compatible material. The best practice is to use Aluminum Bronze for the disc and a high-grade material like Duplex Stainless Steel (e.g., 2205) or Monel for the stem. This ensures the entire assembly has consistent, long-term corrosion resistance in harsh media.
As a source factory with 20 years of experience, we control the entire process from casting to assembly. We conduct Positive Material Identification (PMI) to verify alloy composition, ensure proper heat treatment for optimal properties, and perform rigorous pressure testing to API 598 standards. Full traceability is guaranteed.
Compare our quality against any brand. We're confident you'll choose JRVAL after an in-depth evaluation of our sample products.
We stand by our craftsmanship. Enjoy a comprehensive warranty covering non-human damage, with spare parts readily available.
Every shipment is backed by comprehensive documentation, including material test reports (MTR), heat treatment reports, and mechanical performance tests.
