Cast Steel JIS Storm Valve Vertical Type F3060 10K

Vertical-type storm valve built for robust non-return protection in marine drainage and overboard discharge systems, helping prevent seawater ingress and backflooding when external pressure rises. The vertical configuration supports stable closing behavior and dependable one-way operation in harsh sea conditions. Cast steel body provides high mechanical strength and durability for demanding shipboard service. Manufactured to JIS 10K pressure class with flanged ends for secure installation, repeatable alignment, and efficient maintenance access. Commonly used on bilge and ballast discharge, scuppers, and other storm-water/overboard circuits where backflow prevention is critical.
