Marine Gas System Self Closing Valve – Technical Overview
Application & Function
The sounding self-closing valve is a critical safety device installed on low-pressure gas pipelines aboard ships. It operates autonomously to:
✔ Automatically shut off when pipeline pressure:
-
Drops below minimum threshold (under-pressure)
-
Exceeds safe limits (over-pressure)
✔ Require manual reset after activation (no electrical/external power needed)
Key Installation Requirement
For pipeline-to-hose connections (post-gas meter):
-
Pressure-Loss Protection: Must seal instantly if:
-
Hose disconnects
-
Sudden pressure drop occurs
-
