Oleodinamica Marchesini V1110/VMP RFP3 3/8 C/VMP three-way pressure-compensated flow control valve

Oleodinamica Marchesini V1110/VMP is the RFP3 3/8 C/VMP three-way pressure-compensated flow control valve, with a factory maximum operating pressure of 350 bar and mass of 2.237 kg.

The factory inlet-flow limit is 60 l/min, while the maximum adjusted priority flow is 50 l/min. The pressure compensator maintains the adjusted priority delivery as downstream pressure changes; excess flow is returned to T. The integrated relief limits pressure on the regulated priority circuit. Maximum inlet flow, adjusted flow and component pressure are separate limits.

Connect E to hydraulic supply, P to the circuit requiring regulated priority flow and T to tank. All three threaded ports are 3/8" BSP. Adjust flow with the handknob after releasing the locking nut. The factory standard relief-spring row is 10–180 bar with a 90 bar catalogue setting; this is not a verified preset for a delivered unit and does not replace the 350 bar component rating.

The zinc-plated steel body contains hardened and ground steel parts with standard BUNA-N seals. The original factory hydraulic symbol and exact article drawing are retained in the local PDF. Where the manufacturer describes slight internal leakage, the component is not represented as a zero-leakage shut-off device.

The local technical PDF contains the complete relevant manufacturer spread, including the named article or accessory drawing. Neighbouring valve ratings and optional configurations apply only to the corresponding identified part. Any 50 °C oil temperature and 30 cSt viscosity beside curves are reference conditions.
