Oleodinamica Marchesini V0412/RP18 single Type A counterbalance valve

Oleodinamica Marchesini V0412/RP18 is an actual supplier-listed single Type A counterbalance-valve order designation in the VBCD SE A family. Two independent supplier groups list this complete code; Hydrabuy identifies 1/2 inch BSP connections and a 1:8 pilot ratio for this selected article. These execution details are supplier-stated.

The current manufacturer page and original sheet identify the base V0412 in the same Type A family. The family controls actuator motion and retains an overrunning load in one direction. Its shared construction uses a zinc-plated steel body, hardened and ground steel internal parts and standard BUNA-N seals.

The current factory sources do not explicitly list the full /RP18 order code or certify its 1:8 pilot execution. The original base rows show a 1:4.5 pilot ratio. Their maximum pressure, maximum flow, pressure setting, mass and dimensions have therefore not been assigned to this supplier-listed execution. The supplied setting and revision-specific geometry remain unverified.

The local PDF is a complete manufacturer base-family reference with an applicability note, rather than an RP18-specific rating or dimensional certificate. The manufacturer family image is representative and does not verify the exact supplied pilot construction, connection positions or geometry.
