Under this new structural configuration, Valenti was formally assigned pastoral responsibility over the Northern Sector (Settore Nord) of the diocese. He received his episcopal consecration on 2 May 2026 at the Archbasilica of Saint John Lateran by Pope Leo XIV as a principal consecrator, with Cardinal Baldassare Reina and Cardinal Angelo De Donatis as co-consecrators.
