Valeri scored in the 28th minute off an attempt from the left side of the penalty box to open the scoring for the Timbers, who added two more before the Rapids could get on the board.
The Rapids got a goal from SuperDraft first-round pick Deshorn Brown, who scored off an assist from fellow draft pick and defender Kory Kindle.
The Timbers return to action on Friday against Sporting Kansas City, while the Rapids take on San Jose on Saturday.
