Caution
Because of flow forces, cylinder differential areas, Danfoss recommends Ls margins under 25 bar [360 psi].
As noted above, work port flow is dependent upon the Ls margin set on the pump. PC pumps maintain a
constant discharge pressure which is equal to the PC setting on the pump. Hence the Ls margin for PC
pumps can be thought of as the difference between the PC setting and the load pressure. Therefore work
port flow will change with load pressure, thus, pressure compensated flow will not be obtained.
