Control Hydraulic Valve
"Oil is metered across (feathering lands) notches in the spool before flowing out to the rod end of the tilt cylinders." I did not receive any reply on my Eng>Ita Kudoz question, and I hope you can offer some help in identying the exact part referred.

Metering Lands
In the valve control of hydraulic systems (e.g. of a lift-truck):
"Feathering lands" are actually "Metering Lands" and in a hydraulic system, are a part of the system that enable the flow of the hydraulic fluid to be measured.

This extrax is about Series 34 Sectional Directional Control valves.
It might help:
When assembled in their normal manner the series 34 spool sections are in parallel. When the spools are in neutral position the flow passes by each spool and then onto the tank (outlet) port. If two or more spools are shifted simultaneously their work ports are in parallel, and the oil flow will take the path of least resistance allowing lighter loads to move first. All spool sections are cast with metering notches, and have a high “handle vs. spool” movement ratio, resulting in good metering capability. Input flow can be divided among several circuits (spool sections) by feathering the spools. Series 34 spool sections may also operate in series by installing a series block in between each spool section.
