Ball valves are widely used in marine systems because of their simple structure, tight sealing, and quick operation. In ships, they are often found in bilge systems, ballast systems, and fuel transfer lines, where reliable shutoff is crucial.
To adapt to harsh marine conditions, marine ball valves are manufactured with corrosion-resistant materials like brass, bronze, or stainless steel (316). These materials protect against seawater corrosion and extend service life. Many are coated or lined with epoxy or nickel plating to provide an extra layer of defense.
Another key adaptation is compact design. Space is limited on ships, so marine ball valves are designed with shorter body lengths while maintaining full flow capacity. In addition, floating or trunnion-mounted designs ensure smooth operation even under fluctuating pressure.
From a maintenance perspective, easy disassembly and replaceable seats and seals allow faster repairs at sea. Combined with ISO or DIN standard compliance, these features make marine ball valves a reliable choice for shipbuilders and operators worldwide.
