Oleodinamica Marchesini V0416/SF VBCDF 1/2 SE OMS SF single motor counterbalance valve

Oleodinamica Marchesini V0416/SF (VBCDF 1/2 SE OMS SF) is a single 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 valve controls motor rotation and retains a load in one direction. Connect V1/V2 to the supply and use the original motor-flange connections C1/C2 for the free-flow and controlled sides. The original diagram identifies the controlled return path and the pilot connection.

The direct flange interface is for Danfoss OMS 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 1/8 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.
