JIS 10K Cast Steel Vertical Storm Valves
JIS 10K bronze storm valve is integrally cast from high-quality bronze with outstanding rust and seawater corrosion resistance. The gravity self-closing structure delivers sensitive response and zero-leakage sealing under 1.0MPa medium pressure working conditions.
Overview
Application:It is widely applied for hull scupper drainage and overboard discharge on commercial ships, vessels and marine facilities. It effectively prevents seawater and storm surge backflow to protect internal hull piping systems in complex sea conditions.
