Description

Oleodinamica Marchesini V0660/180 (VS2C 1/2) is a direct-acting sequence valve. The factory pressure rating is 350 bar. Maximum flow is 70 l/min. The exact supplier-listed /180 article uses the factory 10–180 bar spring range, whose catalogue standard setting is 90 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 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.
