Oleodinamica Marchesini V0346 double-acting plough overturning and alignment valve

Oleodinamica Marchesini V0346 is a double-acting plough overturning and alignment valve for a reversible plough with separate alignment and overturning cylinders. The original manufacturer sheet prints this exact code; the operating sequence aligns cylinder B, overturns cylinder A and then returns cylinder B to its working position.

The exact pressure table gives 400 bar maximum component pressure and 230 bar maximum exchange pressure. The sheet describes 150 bar as its catalogue exchange-setting reference; this is not a measured or confirmed delivered setting. A maximum-flow value or cylinder-bore interval is not inferred from the type-label numbers.

The original row gives a 3/8" BSP port reference, L3 of 176 mm and mass of 4.8 kg. The connection prose uses U1/U2 for the alignment cylinder, whereas its threaded-port table labels V1/V2. This notation is kept qualified: use the complete exact hydraulic diagram to identify assembly ports rather than a simplified unverified map.

The body is zinc-plated steel with hardened and ground steel internals and standard BUNA-N seals. These earlier SV/FSM documents are retained on the supplier site; equivalence to later SV XL FS executions is not assumed.

The local PDF preserves the relevant original manufacturer pages and exact article or accessory drawing. Neighbouring assemblies and options apply only to their identified rows. Any 50 °C oil temperature and 30 cSt viscosity shown beside curves are reference conditions, not general operating limits.
