Additional information
Application
Dynamic and energy-saving pump adjustments are achieved by the
combination of a radial piston pump with a high-response valve.
Integration of the pump into a pressure control circuit allows
for realization of dynamic pressure controls. The p/Q closed-
loop control amplifier required for that purpose consists of
a basic card with front plate containing the valve amplifier
with position control as well as an attached daughter card on
which the actual pressure control is realized.

These amplifiers are only supplied as complete combinations.
In connection with the corresponding high-response valve
and pressure sensor, flows can be controlled and pressures
can be regulated in the closed control loop. The input vari-
ables are the pressure p and flow Q command values. Pres-
sure, PL valve spool position and cam position are fed back
as actual values.
