Oleodinamica Marchesini V1126 three-way pressure-compensated flow control valve

Oleodinamica Marchesini V1126 is a three-way pressure-compensated flow-control valve. Both available manufacturer editions identify a 70 l/min maximum flow and a 350 bar maximum component pressure. The controller maintains the selected flow at the priority outlet as pressure changes and sends excess flow to a secondary working line or tank.

The manufacturer specifies a zinc-plated steel body, hardened and ground steel internal parts and standard BUNA-N seals. Both original drawings list 1/2 inch BSP at the A/B connections and 3/4 inch BSP at the connection marked P. When B is used as a secondary working line, its pressure must not exceed the pressure at A.

The same article number appears in two different manufacturer circuit descriptions. The currently linked sheet calls it RFC and does not show a reverse-check branch. The manufacturer-authored sheet attached to the selected supplier offer calls it RFC-VU and explicitly shows that branch. This profile records the common flow-control data and does not certify reverse-check presence or its direction for an unspecified supplied revision.

Connection instructions also differ in their use of E/P and P/A/B labels. The local reference preserves both complete manufacturer spreads; no installation-port mapping is certified by this profile. The manufacturer illustration is representative and cannot establish the internal check-valve execution.
