Routing both pilot lines outside makes the pilot stage independent of the main circuit. The 4WRZE10E1-85-7X/6EG24K31/A1M is built that way, delivers 85 l/min nominal flow and is driven with ±10 V. Weight 8.66 kg.

Benefits
- External pilot oil supply and return through X and Y lines, independent of main pressure.
- 85 l/min nominal flow, up to 170 l/min maximum.
- Spool symbol E1 with internal spool position feedback.
- Command value ±10 V, on-board electronics at 24 V DC.
- 8.66 kg weight at 315 bar maximum operating pressure, UKCA to SI2016/1091.
