JIS 10K Cast Steel Vertical/Angle Storm Valves
JIS 10K cast steel storm valve adopts integral cast steel construction, offering higher impact resistance and pressure tolerance than conventional bronze valves. Its gravity self-closing mechanism ensures rapid reset and tight sealing for long-term stable drainage operation.
Overview
Application:It is widely used for overboard discharge and hull scupper drainage on medium-pressure marine and offshore piping systems. It effectively blocks storm surge and seawater backflow to protect ship internal pipelines under harsh sea working conditions.
