JIS 5K Cast Steel Vertical/Angle Storm Valves
JIS 5K cast steel storm valve adopts integral cast steel structure, featuring higher mechanical strength and pressure resistance than bronze models. It adopts gravity self-closing design, enabling sensitive and tight shut-off to block seawater backflow and wave surge.
Overview
Application:It is mainly used for hull scupper drainage and outer pipeline discharge of various engineering ships and offshore platforms. It adapts to harsh marine environments with strong waves and variable pressures to ensure stable hull drainage operation.
