A large power unit often drives small axes too, and then nominal flow becomes the sizing figure. The 4WRZE16W6-125-7X/6EG24N9ETK31/F1D3M handles 125 l/min here, holds pilot pressure constant with a built-in pressure reducing valve and needs no control lines of its own.
Benefits
- 125 l/min nominal flow in size 16, with the series maximum flow at 460 l/min.
- Integrated pressure reducing valve, keeping control pressure within range even at 350 bar system pressure.
- Internal pilot oil supply and internal return, mounted solely through ISO 4401-07-07-0-05.
- 4...20 mA current command at the on-board electronics, 24 VDC supply.
- Spool symbol W6, concealed auxiliary actuation, NBR seals, weight 12.2 kg, UKCA conformity.
