Oleodinamica Marchesini V0507/090 supplier-listed VAUAC relief valve

Oleodinamica Marchesini V0507/090 is an actual supplier-listed order designation in the VAUAC dual relief-valve family with anti-cavitation. Hikom lists this exact full code as VAUAC 3/8 inch with a 20–90 bar range description. The range is a supplier statement, not a manufacturer-verified spring range or delivered pressure setting.

The current manufacturer original identifies base V0507 in the VAUAC 3/8 inch family. Its shared purpose is pressure limiting in both motor branches with make-up check paths to help prevent cavitation. Shared construction uses a zinc-plated steel body, hardened and ground steel internal parts and standard BUNA-N seals.

The current family sheet does not print the complete /090 code and groups the relevant sizes under different spring ranges. It does not establish the exact supplier-listed 20–90 bar execution. No selected spring range, preset, base pressure/flow rating, mass or dimensions are assigned here. The /090 designation is preserved literally and is not replaced with /180 or merged into the separately offered /160 article.

The local PDF is a complete manufacturer base-family reference with an applicability note. It does not certify the /090 spring, its adjustment travel or pressure calibration. The manufacturer illustration is representative of the VAUAC family and does not identify the internal spring or exact supplied execution.
