Compensated 3 ways flow control valves, with excess oil to pressure
They are used when it is necessary to guarantee a constant flow regardless of the working pressure, the excess oil is sent to a second use under pressure, which is also insensitive to pressure but not to flow.
Setting is made by turning the upper ring nut clockwise or vice versa, locking is ensured by a second lower ring nut screwed in a clockwise direction.
The external body is made of aluminium.
