REXROTH A10VSO PISTON PUMP (A10VSO 28 DFR 31 R P S A 12)

DFR – Pressure and flow control

In addition to the pressure control function, the pump flow may be varied by means of a differential pressure over an orifice or valve spool installed in the service line to the actuator. The pump flow is equal to the actual required flow by the actuator, regardless of changing pressure levels. The pressure control overrides the flow control function.
