The 29-year-old defensive midfielder has spent the majority of his professional career playing outside the top flight, but joined Valencia at the end of last season after his contract with Rayo Vallecano expired.
"Signing for Valencia is the culmination of the work I have put in every year of my career," he said.
"I have had to endure some difficult times and now I'm lucky to have the opportunity of playing European football with a big club like Valencia.
"Joining Valencia is a dream, and so is playing in Europe. The team missed out on the Champions League on the last day of the season and although the Europa League is a small prize for a club like Valencia, I'm very excited about playing in Europe against the best teams in the continent.
"And I hope that in the next three years I will be able to play in the Champions League."
