Oleodinamica Marchesini V0601 VUI 3/8 integrated check valve

Oleodinamica Marchesini V0601 is the VUI 3/8 integrated check valve, listed for maximum flow of 30 l/min and maximum operating pressure of 350 bar. The current factory article table gives a mass of 0.018 kg.

This compact integrated cartridge permits free flow from V to C and blocks reverse flow from C to V. The listed cracking pressure is 1.8 bar. Screw the valve into the correctly machined 3/8" BSP cavity with the flow direction shown in the original hydraulic symbol.

The cavity drawing specifies diameter X of 14.9 mm and a 118-degree seat angle. The valve body diameter D is 14.8 mm, the drawing length L is 18.5 mm and the O-ring size is 10.8 x 1.78 mm. A cavity thread designation does not describe an additional inline pipe connection.

The body is zinc-plated steel with hardened and ground internals and O-ring sealing. The current visible factory table is used for mass and O-ring size; the legacy text embedded in some copies and supplier listings contains different values. No O-ring compound or independent temperature limit is inferred.

The local technical PDF retains the complete applicable original manufacturer spread, including the exact article table, hydraulic symbol and installation drawing. Where curves specify oil at 50 °C and 30 cSt, these are reference conditions rather than operating-temperature limits.
