Open-Center System. In this system, a
control-valve spool must be open in the center to allow pump
flow to pass through the valve and return to the reservoir.
In the illustration below, shows this system in the neutral
position. To operate several functions simultaneously, an
open-center system must have the correct connections, such
as, series, series / parallel connection, and flow divider.
An open-center system is efficient on single functions but is
limited with multiple functions.
