The young Italian rider, with Fixdesign Chablis and Eremo del Castegno, confirmed her excellent recent form with a pair of stylish victories.
With Chablis, she scored 72.68 to claim victory in the Special ahead of France's Karen Tebar and Jill de Ridder of Germany.
Truppa then recorded her best ever result in Freestyle with Eremo del Castegno. She has only ever bettered her score of 79.48 twice in any class - at the World Cup finals in Gothenburg (79.69) and in Vilbach in 2012 (79.95).
"We are more than satisfied with the victories in Fritzens," Enzo Truppa, Valentina's father and coach, said.
"On top of the fantastic results, I have noticed steady technical improvements."
