keep it closed.
When you take a flight or travel from one altitude/pressure to another, the case may be "sucked shut" with the pressure differential. Opening that valve/the knob allows you to equalize the pressure, and open the case without prying it open with a screwdriver/crowbar. Last edited by replicant_argent; 11-10-2010 at 12:51 PM.
