Total price
For rotary drives what matters is a spool freeing the same cross section in both flow directions. The 4WRZE25W6-220-7X/6EG24K31/A1D3M achieves that with spool symbol W6 at 220 l/min nominal flow and operating pressures up to 350 bar.
Benefits
- Spool symbol W6 keeps both flow directions alike, so speed stays stable through a reversal.
- A built-in pressure reducing valve holds pilot pressure constant regardless of working pressure.
- 220 l/min nominal flow in size 25, mounting pattern ISO 4401-08-08-0-05.
- Plus or minus 10 V command, 24 VDC supply through a 7-pole connector (6 + PE) to EN 175201-804.
- UKCA conformity to SI2016/1091 for electromagnetic compatibility, 20.64 kg.
