Oleodinamica Marchesini BS050/300 VMP NG10 CETOP 5 directional-valve subplate with pressure relief

Oleodinamica Marchesini BS050/300 is the VMP NG10 CETOP 5 directional-valve subplate with integrated pressure relief and 3/4" BSP A, B, P and T connections. It is an actual selected supplier article. The factory lists the BS050/000 range placeholder and its spring table; this profile uses the separately offered BS050/300 execution rather than an invented combination.

The size row specifies 100 l/min maximum flow, 250 bar maximum component pressure, an aluminium body and a 1/4" BSP gauge port M. Mount the directional valve on the CETOP 5 / NG10 interface. Connect P to pressure, T to tank and A and B to the actuator; duplicated P and T connections support installation.

The manufacturer spring table gives adjustment range 50–300 bar. The supplier describes this exact BS050/300 offer as 80–300 bar. The differing lower limits remain labelled source references, and no unqualified minimum-setting filter is assigned.

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 1.891 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.
