DR DRG DP DPF DFR DFR1 FR1 Controller for Rexroth A4VSO Series 1x and 30 Piston Pump

PARTS DETAILS:

The pressure controller limits the maximum pressure at the pump outlet within the control range of the variable pump. The variable pump only supplies as much hydraulic fluid as is required by the consumers. If the working pressure exceeds the pressure command value at the pressure valve, the pump will regulate to a smaller displacement to reduce the control differential.

    1. Basic position in depressurized state: V_{g max}.

    2. Setting range for pressure control: 50 to 350 bar. Standard is 350 bar.

The flow controller adjusts the displacement of the pump to the volume required by the consumer. The flow of the pump is then dependent on the cross section of the external metering orifice, which is located between the pump and the consumer. The flow is nearly independent of the load pressure within the control range of the pump. 

Initial position in depressurized state: Vg max Mechanical minimum and maximum swivel angle limitation

    1. The V_{g min} stop is set so that a pressure of 15 to 20 bar is set when port B is plugged.

    2. The V_{g max} stop is set to nominal Vg max. When ordering, please state other setting values in plain text (possible setting ranges Vg max to 50% V_{g max}).
