Oleodinamica Marchesini V1029 DFL 100 - 120 two-way steel flow divider-combiner

Oleodinamica Marchesini V1029 is the DFL 100 - 120 two-way steel flow divider-combiner, with an inlet-flow range of 100–120 l/min and maximum working pressure of 250 bar. The current factory table lists mass 4.380 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 1" BSP supply port and A/B through the 3/4" 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.

The 250 bar working pressure is distinct from the separately stated 300 bar peak pressure. The visible current drawing gives body dimension L of 160 mm, rather than the stale 179 mm entry embedded in some PDF text layers. This size uses the two 8.5 mm mounting holes identified for the 3/4"–1" supply-port range.

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.
