Total price
A speed-controlled hydraulic motor needs the same characteristic in both directions of rotation. The 4WRKE27W6-500L-3X/6EG24ETK31/A1D3M delivers that with spool symbol W6, releases 500 l/min nominal flow and takes the command directly as ±10 V.
Benefits
- ±10 V command, connects directly to existing axis control cards
- Spool symbol W6 with identical behaviour in both control directions
- 500 l/min nominal flow, operating pressure up to 270 bar
- Internal pilot oil supply and internal return
- 19.4 kg in size 27 to ISO 4401-08-08-0-05
