Oleodinamica Marchesini V0665 VS2C 3/4 direct-acting sequence valve

Oleodinamica Marchesini V0665 (VS2C 3/4) is a direct-acting sequence valve. The factory pressure rating is 400 bar. Maximum flow is 110 l/min. The current factory table rates V0665 at 400 bar and lists a 50–400 bar standard spring range, with a catalogue standard setting of 180 bar.

The sequence element admits flow to the next actuator after the pressure threshold is reached. The integrated check provides free return flow. Connect V to supply and C to the actuator, following the two-cylinder application circuit in the local PDF. Downstream load pressure adds to the sequencing requirement; check the circuit rather than treating the set pressure as independent of the second actuator. Catalogue standard settings do not establish the calibration of an individual supplied valve.

The attached current factory sheet is the basis for the 400 bar rating. Older series documents may show different ratings; verify the exact valve execution and document revision before applying a rating to an installed unit.

The manufacturer specifies a zinc-plated steel body, hardened and ground steel internal parts and BUNA N seals. The local technical reference preserves the complete relevant factory spread with the model table, circuit, dimensions and performance curves.
