Where are Pressure Relief Valves (PRV) located?

Pressure relief valves are safety devices that prevent over-inflation by venting excess air automatically. In an inflatable life raft, the air is contained in the tubes, where pressure builds most during inflation or exposure to heat. Putting the valve in the tubes allows quick relief right at the air chambers, protecting the raft from bursting. The canopy, floor, and hull aren’t the places where the primary inflation pressure is managed, so the valve is located in the tubes of the rafts.
