Oleodinamica Marchesini V0348 VRAP 40/50 DE + VMP double-acting plough overturning valve with relief valve

Oleodinamica Marchesini V0348 is the VRAP 40/50 DE + VMP double-acting plough overturning valve with an integrated relief valve. It reverses oil flow automatically to rotate the cylinder of a reversible plough. The exact manufacturer row specifies 250 bar maximum exchange pressure and 250 bar maximum operating pressure.

The assembly combines double pilot-operated load holding with an extension-pressure limiting valve. The reversal control acts at the plough dead point. Connect C1 to the cylinder rod side, C2 to the head side and P and T to the machine supply. The factory identifies this model with its 40/50 cylinder application class; neighbouring 60/80 and larger versions are separate products.

The P, T and C2 connections are 3/8" BSP. The factory C1 entry is a catalogue connection dimension of Ø12 mm. Use the original installation drawing to verify the mating cylinder connection. The body may be mounted in line on the hydraulic cylinder or fixed to the plough structure through the threaded mounting hole.

The zinc-plated steel body contains hardened and ground internals with standard BUNA-N seals and guided-poppet load holding. The exact catalogue row gives mass 3.200 kg and dimensions L 95 mm, L1 58 mm, L2 30 mm, L3 176 mm, L4 72 mm, H 80 mm, S1 35 mm, S2 30 mm and S 65 mm.

The factory describes an exchange setting of about 150 bar and a relief setting of 90 bar as catalogue references. The delivered calibration of the selected supplier stock item is not independently confirmed. These values are not claimed as the actual preset, and no maximum flow is inferred from pressure numbers.

The supplier lists this exact 40/50 model under its stock SKU V0348-S and identifies Oleodinamica Marchesini as the brand. V0348 is the manufacturer code printed in the original table. The meaning of the supplier suffix is not established and is not represented as a separate manufacturer execution.
