14 A7VO Series 63 | Axial piston variable pump
LA1 – Power controller with hydraulically proportional power override
LA1S5 – Power controller with load sensing and
hydraulically proportional LS-override
By connecting an external pilot pressure at port X
possible to override proportionally the differential
pressure Δp of the load sensing control.
Increasing pilot pressure = lower Δp setting.
An example of this is shown in the characteristic curve
below.
Please consult us before carrying out project planning.
