Oleodinamica Marchesini V0282 VRAP 40/50 DE plough overturning valve

Oleodinamica Marchesini V0282 (VRAP 40/50 DE) is a plough overturning valve for automatic reversal of the hydraulic cylinder on a reversible plough. Its factory maximum pressure is 400 bar and maximum exchange pressure is 250 bar. These are separate limits; the exchange pressure is not the valve body pressure rating. The listed mass is 2.130 kg.

The double pilot-operated check arrangement holds the cylinder at an intermediate position. C1 connects to the rod side, C2 to the head side, and P/T to the machine supply. The C1 drawing identifies a 12 mm connection bore, distinct from the G 3/8 threads listed for C2 and P/T.

A pressure-compensated reversal regulator initiates reversal at the plough dead point. The sheet states an approximate supplied exchange pressure of 150 bar, adjustable by the pressure regulator. Use the exact 40/50, 60/80, 80/100, 100/110 or 110/130 execution designation and original cylinder connection drawing when checking suitability.

The zinc-plated steel body contains hardened and ground steel internal parts and standard BUNA-N seals. The guided poppet provides low-leakage load holding. Catalogue dimensions are supplied for installation checks; the type designation is retained without generating optional /CR or other configurations.
