What is a Valve Chest?
A Valve Chest (often associated with sea water intake or “sea chest” line assemblies) is a reinforced section that consolidates critical isolation valves, strainers, and instrumentation for multiple seawater services. It simplifies operation and maintenance while ensuring dependable flow control to downstream systems such as cooling lines, ballast operations, bilge discharge, and firefighting mains.
