Main valve
Also: valve, one-way valve
The packraft is inflated and deflated through the main valve. Many valves have a one-way flap so the air doesn't escape while you inflate.
When inflating, the inflation bag sits on the main valve. A one-way valve lets air in but not out; to deflate it's opened or switched over. Seal (O-ring) and thread should stay clean and free of sand, or the valve will leak. Lost valves or caps are available as spare parts.
Tip: when packing up, open the main valve first and only then the zippers of luggage compartments.
