These valves are used to adjust speed of actuators in one direction; flow is free in the reverse . Pressure compensation is not provided, flow rate depends on pressure and oil viscosity.

Assembly
Connect V to the supply flow and C to the actuator to be controlled. The flow is adjusted from C to V and free in the reverse direction. When used on actuators with double pilot check valves, the VRF has to be mounted between the actuator and the double pilot check valve. Flow adjustments are made by rotating the coupling: clockwise rotation increases the flow and vice versa. Once the flow has been set, tighten the lock nut in order to keep the desired setting in case of vibrations.
Leakage
by diameter combination. Minor leakage with closed valve
