Oleodinamica Marchesini V0910 open-centre three-way diverter valve

Oleodinamica Marchesini V0910 is the DF 3 VIE 1-inch open-centre three-way diverter valve. The current manufacturer technical sheet prints the exact V0910 size row with 1-inch BSP ports, maximum flow 200 l/min and maximum operating pressure 220 bar. The supplied type is independently offered as an open-centre valve by Hikom and Oleokit.

Connect P to the pressure supply and A and B to the alternative circuit branches. Lever position 1 connects P to A; position 2 connects P to B. In the centre position P, A and B are all connected. This standard V0910 open-centre circuit differs from the separately identified V0910/CC closed-centre execution.

The body is cast iron, with hardened and ground steel internals and standard BUNA-N seals. The manufacturer describes minimal internal leakage; no certified zero-leak load-holding claim is made. The current factory base size lists mass 2.5 kg. Envelope dimensions are omitted where older editions differ.

The current manufacturer web page omits bare V0910 from its related-product summary, while its directly linked original DF 3 sheet explicitly prints the article. Current exact supplier offers corroborate the open-centre identity. Older catalogue ratings such as 180 l/min and 250 bar are not assigned to this profile; the current original size row governs.

The local technical PDF should retain the complete current original spread, including the exact V0910 row, open-centre circuit, separate closed-centre option legend and drawing. Oil temperature 50 C and viscosity 30 cSt beside the curves are reference conditions.
