Marchesini 90° flow control valve, to adjust the speed of an actuator in both directions.
The VRFB regulates the speed of a cylinder or motor in both directions. It is not compensated: the flow through it depends on the pressure and oil viscosity, but the adjustment is very fine. It is set with the aluminium knob, after loosening the side locking screw.
One port connects to the supply and the flow is regulated at the other. If the actuator has a pilot-operated check valve, the VRFB goes between the actuator and that valve. When closed, the needle lets no oil through.
Zinc-plated steel body, hardened and ground steel internals, NBR seals.
