Oleodinamica Marchesini V1220 VRSP 1/2 regenerative hydraulic valve

Oleodinamica Marchesini V1220 (VRSP 1/2) is a regenerative hydraulic valve with 1/2 inch BSP main ports. Its factory ratings are 60 l/min maximum flow and 350 bar maximum operating pressure.

During regenerative operation the valve routes oil from the cylinder rod side at C1 into the head-side supply at P, adding return oil to pump delivery. When head-side pressure reaches the selected setting, regeneration is cut out and the circuit returns to full-force operation. The factory regeneration setting range is 50–100 bar; this range is separate from the 350 bar maximum operating pressure.

Connect C1 to the rod side, P to the head-side supply and M to an optional pressure gauge. Follow the complete original circuit diagram for V1 and the directional valve connections. The listed pressure range does not identify a particular delivered adjustment setting.

The zinc-plated steel body contains hardened and ground steel internal components and standard BUNA N seals.
