Oleodinamica Marchesini V0560 VRF 1/2 one-way flow control valve

Oleodinamica Marchesini V0560 (VRF 1/2) is an in-line one-way flow control valve with 1/2 inch BSP connections. The manufacturer lists a maximum flow of 70 l/min and a maximum pressure rating of 300 bar. These ratings identify separate selection limits; use the original performance curves and installation details to check the operating point.

The barrel throttle meters flow from C to V and provides a check-valve bypass for reverse flow from V to C. It is not pressure compensated: the resulting flow changes with pressure difference and oil viscosity. Rotate the outer sleeve to adjust flow, then secure the locking ring. When used with a pilot-operated check valve, install the regulator between the actuator and that check valve. The listed check-valve cracking pressure is 0.5 bar.

The body is zinc-plated steel with hardened and ground steel internal parts. The manufacturer specifies BUNA N seals. Reference curve conditions are 50 °C oil temperature and 30 cSt oil viscosity. The local reference includes the complete relevant manufacturer spread with its code table, hydraulic schematic, dimensions, curves and conditions.
