Beschreibung
Zusammenfassung:	A system for controlling an independent metering valve having a pair of independently controlled electrohydraulic displacement controlled spool valves for controlling pump-to-cylinder communication between an inlet port and a pair of control ports and another pair of independently controlled electrohydraulic displacement controlled spool valves for controlling cylinder-to-tank fluid flow between the control ports and an outlet port. The spool valves of the independent metering valve are calibrated to provide the required fluid flow.
