Description

Oleodinamica Marchesini V1121 (RFP3 1/2 OMP/OMR) is a motor-mounted priority flow control valve. The factory pressure rating is 350 bar. Maximum inlet flow is 60 l/min and maximum regulated flow is 50 l/min. These are different limits; the pressure rating does not specify the outlet setting.

This version has a direct mounting interface for Danfoss OMP/OMR motors. Fit M1 and M2 to the matching motor ports and connect P and T as shown in the factory circuit drawing. The regulator directs surplus inlet flow to the tank-return path. Confirm the motor interface and return-line conditions against the original drawing; the family name alone does not establish compatibility with every motor execution.

The manufacturer specifies a zinc-plated steel body, hardened and ground steel internal parts and BUNA N seals. The local technical reference preserves the complete relevant factory spread with the model table, circuit, dimensions and performance curves.
