Oleodinamica Marchesini V0425/SF VBCDF 1/2 DE OMP-OMR SF double motor counterbalance valve

Oleodinamica Marchesini V0425/SF (VBCDF 1/2 DE OMP-OMR SF) is a double motor counterbalance valve rated for 50 l/min maximum flow and 350 bar maximum operating pressure. Its factory pilot ratio is 1:4.5. The manufacturer lists a standard setting of 320 bar; this catalogue setting is separate from the maximum pressure rating.

The two counterbalance sections control load-driven motor rotation and retain the load in both directions. Connect V1/V2 to the supply and C1/C2 to the motor flange. Pilot pressure opens the corresponding controlled return path; the integrated check paths admit supply flow. Follow the original hydraulic schematic for both motor directions.

The direct flange interface is for Danfoss OMP/OMR motors. V1/V2 supply connections are 1/2" BSP; the C1/C2 motor-interface passages have a listed 9 mm bore and O-ring sealing. Check the original drawing for the exact mounting pattern.

The /SF article includes the brake-release function and a dedicated SF connection of 1/4 inch BSP. This is a separately listed complete code. The source schematic labelled with brake release applies to this /SF execution.

The manufacturer specifies a valve setting at least 1.3 times the load-induced pressure. Check the circuit setting against the actual load; no customer-specific adjustment or /P or /PP option is inferred from this standard article code. The body is zinc-plated steel with hardened and ground steel internals and standard BUNA N seals.
