You're confusing projection with actuated skills.
Valle projects to be a starter with adequate defense, good power, and an adequate hit tool. What he actually is right now is a rough defender with a poor plate approach.
It remains to be seen how close Valle can get to his ceiling, but that does seem to be a steep price for a guy like Lopez.
I would guess it's Schwimer plus another reliever like Diekman or Stutes.
