What device allows excess gas/pressure to escape from the raft?

Excess gas inside an inflatable raft must have a safe way to escape so the raft doesn’t over-pressurize and fail. A pressure relief valve is built to open automatically at a set internal pressure, venting air until the pressure drops to a safe level and then resealing. This keeps the raft structurally intact and maintains buoyancy as conditions change, such as heating from sun or movement that warms the gas. Other devices either vent liquids, rupture permanently, or require manual action, so they don’t provide the reliable, automatic, resealing relief that a pressure relief valve offers.
