After attending the Military Academy of Modena and the School of Application of artillery and Engineers, on 5 September 1907 he was commissioned as second lieutenant.

[4][5][6] After the establishment of the Regia Aeronautica in 1923, Valle joined the new armed force with the rank of colonel, assuming the position of commander of the airship group.

[7][8][9][10][11] After assuming office, Valle wrote Mussolini a secret report in which he showed that Balbo had inflated the figures on the numbers of available aircraft – a practice he would be in turn accused of by his successor, Francesco Pricolo, years later.

On that occasion Valle proposed to suspend the sale of a batch of Savoia-Marchetti S.79 bombers to Yugoslavia, diverting them to the Regia Aeronautica, but was not listened.

[12][13][14] After the end of the Second World War, Valle was tried for having exploited his position for illicit enrichment and for having fascistized the Italian Air Force, but was acquitted in 1947.
