The Brazilian keeper featured eight times for Juventus last season but played as an understudy to Gianluigi Buffon and a move to Spanish side Valencia has now materialised.
Having spent two years with the Italian champions, Neto failed to establish himself as a first-choice keeper but his move to Mestalla will now seem him re-find first team football as current number one Diego Alves looks set to leave.
Alves, who was in superb form last season looks likely to join Napoli this summer, whilst Matthew Ryan left for Championship side, Brighton.
Having begun his career in Brazil, Neto moved to Europe with Fiorentina in 2011 after impressing for the Brazilian U23 national side, with whom he helped gain a silver medal at the 2012 Olympic Games.
Having made 71 league appearances for the Florence-based side – he would then move to Juventus.
