Monel Subsea Marine Forged Corrosion Resistant Floating Ball Valve

Product Overview

The Monel Marine engineering forged steel corrosion-resistant floating ball valve is a high-end special valve specially designed for harsh Marine environments. Adopting Monel nickel-copper alloy (UNS N04400) as the core material, combined with forging forming technology and floating ball structure, it provides outstanding corrosion resistance and reliable operational performance in high-pressure and highly corrosive submarine environments, making it the ultimate solution for submarine pipeline systems, offshore platforms and Marine engineering.

Technical specifications
