Oleodinamica Marchesini V0582 VRFU 90° 3/8 unidirectional flow control valve

Oleodinamica Marchesini V0582 (VRFU 90° 3/8) is a unidirectional flow control valve. The factory lists a 350 bar working-pressure limit. Maximum flow is 30 l/min, with 3/8 inch BSP ports arranged at 90 degrees. This execution has no pressure compensation; flow changes with pressure difference and oil viscosity.

The throttle meters flow from C to V and the internal check provides a free-flow path from V to C. The check opening pressure is 0.5 bar. Connect V to supply and C to the actuator. When used with a pilot-operated check valve, install the regulator between that valve and the actuator.

Loosen the side locking screw before turning the hand knob, then secure the setting. The 1/4, 3/8 and 1/2 inch standard versions use a blue plastic knob; an aluminium knob is a separately ordered /AL execution and is not implied by these unsuffixed article codes.

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