Salazar and Triay had faced Ortega and Gonzalez 11 times before, but never in a final, and were down a set after conceding the tie-break.
In what was their seventh final in a row, the Spaniards came back in style, eventually breaking twice in the final set.
Salazar is the third player ever to win 50 World Padel Tour titles after Fernando Belasteguin (65) and Pablo Lima (50), while Triay is now the woman with the second-most titles behind only her team-mate with 33.
