The purge valve is used for crankcase and (fuel) evaporative emissions control system.  Simple put, it burns vapors that collect in the "crackcase" (i.e. - from the oil filler neck and oil pan) and vapors collected in the charcoal canister.

The black, plastic valve tends to crack, so it needs to be immediately replaced if found damaged.
