P/V valves & cargo venting
압력·진공 밸브 및 벤트
Pressure/vacuum valves on each cargo tank that let the tank breathe: they release excess vapour pressure and admit air when pressure drops, protecting the tank structure from bursting or collapsing.

- Family reference-profile markers
- ● 4 Standard · ○ 0 Common · △ 1 Variant · 16 unmarked
- Component coverage
- 2 released source-BOM records
- Relationship meaning
- Family markers describe reference applicability. Component links are released source-BOM listings and do not assert complete engineering containment.
FAMILY REFERENCE APPLICABILITY
Family profiles carrying a source marker.
Unmarked Families are not listed; an unmarked cell means “not normally fitted” in the source Family profile, not confirmed absence from a vessel.

P/V valves
P/V 밸브The pressure/vacuum valve on each tank that opens outward at set overpressure and inward at set vacuum, protecting the structure while keeping the tank normally sealed.
