Oleodinamica Marchesini V0890/CC closed-centre three-way diverter valve

Oleodinamica Marchesini V0890/CC is the 1/2" BSP closed-centre DF 3 diverter. The original V0890 row gives maximum flow 90 l/min and maximum pressure 250 bar. The exact supplier catalogue row explicitly names the complete /CC article, and the original CODE/CC legend identifies the closed-centre execution.

Connect P to supply and A/B to the alternative circuit branches. One lever position connects P to A, the other P to B. At the centre position the selected /CC circuit blocks P, A and B. The standard open-centre diagram elsewhere on the sheet does not define this selected execution.

The body is cast iron, with hardened and ground steel internals and standard BUNA-N seals. The factory describes minor leakage; no zero-leak load-holding certification is inferred. The original unsuffixed size-row mass is retained only as a base-execution reference, not a separately weighed /CC assembly.

The local PDF retains the complete relevant original manufacturer spread, including the size row, option legend, hydraulic diagram, curves and drawing. Adjacent executions apply only to their identified rows. Oil temperature 50 C and viscosity 30 cSt beside the curves are reference conditions, not operating limits.
