Latin "v" pronounced like English "w" is the old, original pronunciation.
During the evolution of the language, the pronunciation of Latin "v" has changed to that of English "v", so this is how all Romance languages pronounce it.
Actually the sound "v" did not exist in the ancient Indo-European languages, but only the English "w".
The change in pronunciation from "w" to "v" has affected most European languages, not only those descended from Latin, unless they have lost completely the original "w", like Greek.
English is an exception where the ancient pronunciation of "w" has been conserved, even if other sounds have changed more than in most languages.
