Oleodinamica Marchesini V1025 DFL 25 - 40 two-way steel flow divider-combiner

Oleodinamica Marchesini V1025 (DFL 25 - 40) is a two-way steel flow divider-combiner. The factory lists a 250 bar working-pressure limit. The inlet-P flow range is 25–40 l/min. Peak pressure is 300 bar, distinct from the 250 bar working limit. Port P is 1/2 inch BSP and both A and B are 3/8 inch BSP.

The spool divider sends inlet flow to two nominally equal branches and combines return flow in the opposite direction. It is intended for two matching actuators supplied by one pump and controlled by one directional valve, without a mechanical link between the actuators. Connect P to the supply and A/B to the actuator branches.

The factory states a maximum error of ±3% calculated against maximum flow; this is not a promise of ±3% relative accuracy at every operating flow. Cylinder synchronisation errors are compensated at the end of stroke. Select within the stated total inlet-flow range, rather than interpreting the model numbers as flow per outlet. The spool uses matched clearances with minimal leakage, not a positive shut-off seal.

The manufacturer specifies a zinc-plated steel body with hardened and ground steel internal parts. Seals are BUNA N and PTFE.
