Oleodinamica Marchesini V1012KIT weld-on double pilot-operated check valve kit

Oleodinamica Marchesini V1012KIT is the factory-listed VBAS 90 double pilot-operated check valve kit for welding directly to a cylinder. The exact KIT code is printed in both the original performance and dimensional tables. Its row gives pilot ratio 1:5.5, maximum flow 25 l/min, maximum component pressure 350 bar, cracking pressure 3 bar and mass 3.382 kg.

The supplier explicitly identifies body, pilot stem and check cartridge in the kit. The manufacturer supplies the stem and cartridge unassembled so they can be fitted after the body is welded onto the actuator. This is the named complete kit, not an empty housing or an assembled hydraulic cylinder.

V1/V2 are the 3/8" BSP supply connections; the C-side interfaces are welded to the actuator as shown in the original circuit and drawing. The nominal VBAS 70/80/90 designation is retained as a factory size name and is not converted into an unprinted cylinder-bore diameter. V1011KIT is single controlled direction; V1010KIT and V1012KIT are double controlled directions.

The weldable body is steel with hardened and ground internal parts and standard BUNA-N seals. Follow the original welding and subsequent cartridge/pilot installation sequence. The representative family image may show the assembled arrangement; the delivered stem and cartridge condition is identified above.

The local technical PDF retains the complete relevant original manufacturer spread, including the exact size or kit row, option legend, hydraulic circuit and installation drawing. Adjacent executions apply only to their named rows.
