Seawater Desalination Without the Corrosion: Long-Life Ceramic Valve Cores
Seawater is one of the toughest environments for any valve. Chloride ions attack metals, and marine organisms attach to surfaces, causing blockages and wear. Maintenance costs add up quickly.

Alumina ceramic valve cores are made for this challenge. They resist chloride attack, with annual corrosion below 0.001 mm in a 50 ppm Cl⁻ environment. Their specially designed surface also reduces biofouling attachment by more than 95%, helping flow remain smooth and stable.

Flow design adds more value. CFD-optimized low-turbulence channels cut pressure loss by 40% and raise flow by 15%, which can improve system efficiency. A V-notch anti-cavity structure reduces cavitation damage by 90%, protecting both the core and downstream components.

For desalination plants, this means longer service intervals, less downtime and more predictable operating costs. The same advantages carry over to water treatment and purification systems, where reliability is critical.
