On flow-controlled axes the characteristic curve determines how the machine feels. The 4WRKE25R220L-3X/6EG24K31/F1D3M uses spool symbol R with a linear curve and meters 220 l/min nominal flow, supplied from an external pilot circuit.
Benefits
- Linear characteristic of symbol R for even response across the stroke
- 220 l/min nominal flow against a maximum of 870 l/min
- External pilot oil supply and external return
- 4...20 mA command, 24 VDC supply, on-board electronics inside the valve
