Oleodinamica Marchesini V0500/SF180 dual-branch motor relief valve with brake release

Oleodinamica Marchesini V0500/SF180 is a dual-branch motor relief valve with brake release with 1/2" BSP connections. The applicable original V0500/SF circuit row gives 60 l/min maximum flow and a 350 bar component limit. The exact supplier type explicitly prints the 10-180 bar spring range, matching the original spring table. The adjustment is by screw.

The mounting family is intended for Danfoss OMP/OMR motors. Flange M1/M2 to the matching motor interface and connect V1/V2 to supply according to the original drawing. The DE circuit provides crossed pressure relief for both motor branches. Named series compatibility does not independently confirm every shaft, port or mounting variant.

The selected SF execution has a brake-release connection. The exact original SF row specifies a 1/8" BSP SF port and its separate circuit is retained in the local PDF. SF denotes brake release, not the anti-cavitation AC execution.

The original specification uses a zinc-plated steel body, hardened and ground steel internals and standard BUNA-N seals. Mass is a labelled reference for the matching original circuit row, not an independently weighed handknob or sealing-cap option. No delivered preset is inferred from catalogue standard settings. The genuine representative family photograph may show the standard DE or screw-adjusted body; the actual SE/DE/SF circuit and selected adjustment follow the named article and original diagrams.

The local PDF retains the complete relevant original spread, with its exact circuit row, spring/adjustment legend, hydraulic symbol and mounting drawing. Adjacent executions apply only to their named rows. Oil temperature 50 C and viscosity 30 cSt beside curves are reference conditions, not operating limits.
