Oleodinamica Marchesini V0455/SF180 supplier-listed AG-AR relief valve

Oleodinamica Marchesini V0455/SF180 is an actual supplier-listed order designation in the VAU AG-AR motor-valve family. Hikom identifies the complete code as a nominal 1/2 inch AG-AR execution with an SF brake-release designation. These execution details are supplier-stated; the exact SF circuit and brake-release connection are not established by the available original drawings.

The manufacturer documents base V0455 as a motor-flange cross-line relief-valve family for Samhydraulik AG-AR motors. The manufacturer base-family reference specifies a zinc-plated steel body, hardened and ground steel internal parts and standard BUNA-N seals; construction of the supplied SF execution is not independently confirmed.

The current original lists V0455 and depicts the standard relief arrangement. A supplier-retained earlier manufacturer sheet captions its diagram as having brake release, but does not identify a separate SF article row or labelled brake-release port. That caption is not treated as an SF circuit certificate. The standard circuit, pressure and flow ratings, mass, dimensions, mounting-bolt arrangement and pressure setting have not been assigned to this SF order designation. The 180 suffix is retained without interpreting it as an operating-pressure limit or delivered preset.

The local PDF preserves the complete relevant current and earlier manufacturer family pages with their limitations. The manufacturer illustration represents the base VAU AG-AR family and does not verify the SF supplied geometry or brake circuit.
