Mario Mandzukic scored his third goal in as much Juventus games, or killed in Valencia to win the last 16 of the Champions League qualification.
The Kroätk played in his first Champions League goal because his fight against Real Madrid in the final fourth season was the fourth final after Cristiano Ronaldo's empty ball over the box.
The Italian champions could be a lot in the first half with a front three of Paulo Dybala, Mandzukic and Ronaldo unable to break the Spanish side.
However, they improved after the break and the result, in combination with Manchester United's victory over Young Boys, means that Valencia is denied.
The visitors were the best chance for the game just six months when the defense Mouktar Diakhaby saved his headline from a corner in a point-blank row by former Arsenal War Wojciech Szczesny.
That miss was to be costly when Mandzukic won the # 39 winner in # 39; After 59 minutes, Ronaldo left half a bit hard work to put a pen in a box.
Valencia, however, found that they had done a minute later, but Diakhaby's header was rejected to stop his hand.
The result is Juventus – finalists in two of the last four years – have retained a serious magazine in six of their last seven Champions League group games.
