Oleodinamica Marchesini BS030/300 VMP NG6 CETOP 3 directional-valve subplate with pressure relief

Oleodinamica Marchesini BS030/300 is the VMP NG6 CETOP 3 directional-valve subplate with integrated pressure relief and 3/8" BSP A, B, P and T connections. It is an actual selected supplier article. The factory lists the BS030/000 range placeholder and its spring table; this profile uses the separately offered BS030/300 execution rather than an invented combination.

The size row specifies 40 l/min maximum flow, 250 bar maximum component pressure, a zinc-plated steel body and a 1/4" BSP gauge port M. Mount the directional valve on the CETOP 3 / NG6 interface. Connect P to pressure, T to tank and A and B to the actuator; duplicated P and T connections support installation.

The selected spring range is 80–300 bar, matched to the actual offer and the factory spring table.

The factory standard-setting reference is 150 bar, with approximately 50 bar pressure increase per turn at the stated 4 l/min reference flow. These are catalogue references, not confirmation of a delivered preset. The spring adjustment endpoint does not override the separately stated 250 bar component limit; a range extending to 300 bar must not be read as permission to operate the subplate above 250 bar.

Internal parts are hardened and ground steel, with standard BUNA-N seals and guided-poppet sealing with minor leakage. The common size row lists mass 2.062 kg. Handknob and sealing-cap suffixes identify other adjustments; none is appended to this actual screw-adjusted article.

The local technical PDF retains the complete relevant original factory spread, including the applicable row, spring table or material-code convention, hydraulic symbol and drawing. Neighbouring executions apply only to their identified rows. Oil temperature 50 °C and viscosity 30 cSt beside curves are reference test conditions rather than operating limits.
