Oleodinamica Marchesini V1034 DFL A CARTUCCIA 15-40 LPM two-way steel flow divider-combiner — cartridge design

Oleodinamica Marchesini V1034 is the DFL A CARTUCCIA 15-40 LPM two-way steel flow divider-combiner, with an inlet-flow range of 15–40 l/min and maximum working pressure of 350 bar. The current factory table lists mass 0.986 kg.

The valve divides the incoming P flow into equal 50:50 branches at A and B and combines the returning flows in the opposite direction. It is intended for two equal actuators without a mechanical coupling, supplied by one pump and operated by one directional valve, which must move together in extension and retraction.

Connect P through the 3/8" BSP supply port and A/B through the 3/8" BSP actuator ports. The flow range applies to the inlet; it is not the flow assigned independently to each branch. The factory tolerance is ±3% of maximum flow, with synchronisation differences compensated at cylinder end of stroke. Matched clearances allow slight leakage, so this device is not an independent zero-leakage load-holding valve.

This is the DFL C cartridge-design version, whose exact table designation is DFL A CARTUCCIA. The illustrated supplied component has a ported steel body with P/A/B connections; it is not represented as a bare screw-in cartridge. The current factory table gives 350 bar working pressure but leaves the peak-pressure column unresolved, so no peak-pressure value is assigned.

The zinc-plated steel body contains hardened and ground steel components with BUNA-N and PTFE seals. The full original local sheet includes the hydraulic symbol, exact flow-range table and installation dimensions.

The local technical PDF retains the complete applicable original manufacturer spread. Neighbouring sizes and optional configurations apply only where explicitly identified. Any 50 °C oil temperature and 30 cSt viscosity shown with curves are reference conditions rather than independent operating limits.
