Total price
On a new build, internal piloting saves pipe runs and interfaces. The 4WRZE25W8-220-7X/6EG24ETK31/A1M draws pilot oil from the main circuit and returns it there, converts 220 l/min nominal flow and admits 870 l/min at most.
Benefits
- Internal pilot oil supply and internal pilot oil return, minimal piping
- 220 l/min nominal flow at 350 bar operating pressure
- Maximum flow 870 l/min in size 25
- Spool symbol W8 with three switching positions and four ports
- On-board electronics of version 6EG24ETK31, command value ±10 V, 24 VDC supply
