Web tension and winding force need small, exact oil volumes and a stable pilot pressure. The 4WRTE10W8-25L-4X/6EG24K31/A1M supplies a 25 l/min nominal flow, follows a plus/minus 10 V command and is piloted externally.

In winding applications small corrections decide web tension, and a drifting pilot pressure ruins them. The 4WRTE10W8-25L-4X/6EG24K31/A1M therefore draws pilot oil externally and meters a 25 l/min nominal flow.
Advantages
- Nominal flow of 25 l/min for fine corrections of force or speed commands.
- External pilot oil supply and external return for constant pilot pressure.
- Plus/minus 10 V command, negative setpoints are followed without switching over.
- Operating pressure up to 350 bar, flow up to 170 l/min.
- Spool symbol W8, three switching positions, connection diagram ISO 4401-05-05-0-05.
- Weight of 8.5 kg, NBR seals, HL hydraulic fluid.
