Linear oil flow depending on spool type
U
S
= Signal voltage; U
DC
= Supply voltage; 1 = First PVB after PVP; 8 = Eighth PVB after
Pressure-compensated PVB, open center PVP
The oil flow is dependent on the supplied pump oil flow.
The characteristics are plotted for a pump oil flow, Q
P
, corresponding to the rated maximum spool oil
flow, QN. Increasing the pump oil flow to 1,4 × Q
N
will give the same oil flow on the eighth as on the first
basic module.
The letters AA, A, B, etc. denote spool types. The characteristic below is shown for spool travel in both
directions. All other characteristics are shown for spool travel in one direction only.
