When an axis has to be fed in small steps while the circuit still holds 350 bar, nominal flow decides the resolution. The 4WRTE10E1-25L runs a 25 l/min nominal flow in size 10 and takes its command as a plus/minus 10 V voltage signal on the on-board electronics.

Total price
On feed movements measured in tenths of a millimetre, nominal flow governs how finely the axis can be positioned. The 4WRTE10E1-25L-4X/6EG24K31/A1M meters 25 l/min on the ISO 4401-05-05-0-05 interface and corrects spool travel through internal position feedback.
Advantages
- Nominal flow of 25 l/min in size 10, so every command step releases a correspondingly small oil volume.
- Plus/minus 10 V command fed straight from the analogue card to the on-board electronics, no separate amplifier required.
- External pilot oil supply and external pilot oil return keep pilot pressure independent of the load pressure at port P.
- Operating pressure up to 350 bar, flow up to 170 l/min at fully opened spool.
- Spool symbol E1 with three switching positions on four ports, subplate mounting to ISO 4401-05-05-0-05.
- Weight of 8.44 kg, NBR seals, 7-pole connector (6 + PE) to EN 175201-804.

Applications
Typical duties are feed and positioning axes that need small oil volumes metered accurately. The external pilot supply suits circuits in which system pressure fluctuates or drops temporarily. HL fluid and NBR seals match standard mineral oil hydraulics in machine building.
