Oleodinamica Marchesini V0136/SE/SX VBPSE 1/2 L C/RUB. 2 CC single pilot-operated check valve with manual shut-off

Oleodinamica Marchesini V0136/SE/SX is the VBPSE 1/2 L C/RUB. 2 CC single pilot-operated check valve with integrated left-side manual shut-off and 15L DIN 2353 actuator connections. The selected commercial article uses the exact /SX execution; the asterisk beside the factory base code is a fittings footnote rather than a character in the order code.

The exact factory row gives maximum flow 50 l/min, maximum operating pressure 350 bar, pilot ratio 1:5 and cracking pressure 3 bar. V1 and V2 have 1/2" BSP supply connections; C1 and C2 are the DIN 2353 actuator connections for 15 mm outside-diameter tube. No unprinted metric thread size is inferred from the DIN designation.

Connect C1 to the free-flow side of the actuator and C2 to the side where return-flow holding is required. The single pilot-operated check holds flow in one direction until pilot pressure permits release.

The integrated manual shut-off can isolate flow after stabiliser legs are lowered. The drawing is the left-side version; the manufacturer describes a reversible lever. Body material is zinc-plated steel, with hardened and ground internals and standard BUNA-N seals. Guided-poppet sealing has negligible leakage.

Exact catalogue dimensions are L 90 mm, L1 164 mm, L2 45 mm, H 75 mm and S 35 mm; listed mass is 1.752 kg. Values apply to this exact single or double DIN execution. They are not copied from the BSP-only neighbouring row.

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.
