Oleodinamica Marchesini V0705/180 VRPRL 3/8 direct-acting pressure reducing valve with check valve

Oleodinamica Marchesini V0705/180 (VRPRL 3/8) is a direct-acting pressure reducing valve with check valve. The factory pressure rating is 350 bar. Maximum flow is 30 l/min, with a 35–180 bar pressure-adjustment range. This exact /180 screw-adjusted execution is listed as a complete article by a supplier; the factory sheet defines the base body, spring range and adjustment options.

Connect P to the main pressure line, Reg. to the circuit requiring lower pressure and T to tank. The reducing element controls downstream pressure. The 350 bar inlet/body limit is distinct from the 35–180 bar regulated-pressure range. The factory lists internal leakage of 70 cm³/min with 350 bar applied at P; this is a test-specific value, not a zero-leakage or pressure-holding claim.

An integrated check valve permits free reverse flow. This reverse-flow path is the defining difference from the corresponding VRP version.

The manufacturer specifies a zinc-plated steel body, hardened and ground steel internal parts and BUNA N seals.
