The Pressure Relief Valve is an important safety mechanism for the locking watertight enclosures and also adds a few features to the enclosures. In the rare situation that an excessive amount of pressure builds up in the tube it can create an unsafe situation and/or damage to the enclosure. The PRV is designed to work with the updated Vacuum Plug and Backfill Adapter.

In the rare situation that an excessive amount of pressure builds up in the tube it can create an unsafe situation and/or damage to the enclosure. Pressure build-up could be due to the buildup of gasses from a chemical reaction like something catching on fire, or from a slow leak into the enclosure while at depth followed by a quick return to the surface. The PRV automatically releases any excess pressure built up inside a watertight enclosure. It works automatically to relieve pressure, and it also works manually, like the original vent.

Note: if you already have a vacuum plug, you will need the updated version to be compatible with the PRV.
