Oleodinamica Marchesini V0920/CC closed-centre six-way diverter valve

Oleodinamica Marchesini V0920/CC is a closed-centre six-way diverter valve with 3/8" BSP connections, 60 l/min maximum flow and a 300 bar component limit. The full offered code is explicitly listed by the factory and supplier. The original V0920 size row supplies the body rating; the printed CODE/CC closed-centre legend defines the selected centre execution.

The DF 6 couples two three-way sections under one lever. Connect P and P′ to the respective supply lines and A/B and A′/B′ to the two actuator circuits. One working position connects P–A and P′–A′; the other connects P–B and P′–B′. The selected /CC centre blocks the ports in each section. No cross-connection between the independent supply sections is inferred from the open-centre description of the standard version.

The body is cast iron, with hardened and ground steel internal parts and standard BUNA-N seals. The factory describes minor internal leakage; the diverter is not represented as a certified zero-leak load-holding valve. Unqualified envelope dimensions are omitted where legacy text layers and the visible drawing differ. Any base-row mass shown is labelled as a base-execution reference.

The local technical PDF retains the complete relevant original manufacturer spread, including the size table, option legend, hydraulic circuit and drawing. Neighbouring executions apply only to their identified rows. Oil temperature 50 °C and viscosity 30 cSt shown beside curves are reference conditions.
