At small command values every fluctuation of the pilot pressure shows up. The 4WRZ10W8-25-7X/6EG24N9TK4/D3M therefore takes its pilot oil from an external source and controls 25 l/min nominal flow at 315 bar.

Total price
In the lower command range a varying pilot pressure is noticed at once. The 4WRZ10W8-25-7X/6EG24N9TK4/D3M therefore feeds its pilot stage externally and works at 25 l/min nominal flow in size 10.
Benefits
- External pilot oil supply, internal return, an even pilot pressure at small command values.
- 25 l/min nominal flow, 170 l/min maximum at 315 bar operating pressure.
- Pressure reducing valve in the pilot stage for a defined pilot pressure.
- Spool symbol W8, 3 switching positions, 4 ports in size 10.
- 8.24 kg, 24 VDC, NBR seals, 7-pole plug (6 + PE) to EN 175201-804.

Applications
The valve is wanted on axes with slow creep motion, during setup and positioning. The external pilot source keeps the pilot pressure up even at low system pressure. The small nominal step improves resolution in the lower third of the characteristic.
