Is the word valoriza the same in Brazilian and European Portuguese?

Yes

The word "valoriza" is identical in meaning, grammar, and spelling in both Brazilian and Continental Portuguese. The only difference lies in pronunciation. In Brazilian Portuguese, the vowels are generally more open and the rhythm is more melodic and vocalic. In Continental Portuguese, the vowels (especially unstressed ones) are much more closed or even reduced, and the rhythm is more stress-timed, which can make the word sound more "clipped" or "shortened" to a Brazilian ear.
