In workshops full of frequency converters and long cable trays a voltage command loses accuracy. The 4WRZE25W8-325-7X/6EG24K31/F1D3M therefore accepts a 4 ... 20 mA current signal and turns it into 325 l/min nominal flow at 350 bar.
Benefits
- A 4 ... 20 mA current command is immune to voltage drop and induced interference.
- 325 l/min nominal flow against 870 l/min maximum, for cylinders of large swept volume.
- External pilot oil supply and external pilot oil return for plants with their own pilot circuit.
- The integrated pressure reducing valve holds pilot pressure steady at system pressure up to 350 bar.
- Spool symbol W8 with a defined centre condition, mounting pattern ISO 4401-08-08-0-05.
