This is from sweet maria's..."The 3-Way Valve: this does cost more. Do you need a 3-way valve to make perfect espresso? No! But it means the machine automatically releases high tank pressure so the "puck" is drier after extraction, and you can clean the machine by backflushing. Note that Gaggia USA does not officially support backflushing because it may splash hot water out the release valve into the drip tray. This is a legal concern - you can backflush but you do it at your own risk."
