When the tank return carries back pressure, the pilot drain belongs outside. The 4WRZE10W8-50-7X/6EG24EK31/A1M feeds internally and drains externally, at 50 l/min nominal flow and a ±10 V command value. Weight 8.02 kg.

Back pressure in the tank return distorts the pilot stage if the pilot oil is drained internally. The 4WRZE10W8-50-7X/6EG24EK31/A1M therefore takes pilot pressure internally from the main circuit but drains the pilot oil externally through the Y line, at 50 l/min nominal flow.
Benefits
- Internal pilot oil supply with external drain, Y line to tank without pressure.
- 50 l/min nominal flow in size 10, up to 170 l/min maximum.
- Spool symbol W8 with three switching positions.
- Command value ±10 V, on-board electronics at 24 V DC.
- 8.02 kg weight at 315 bar maximum operating pressure, UKCA to SI2016/1091.
