The larger the flow, the more the back pressure in the return matters. The 4WRZE25W8-325-7X/6EG24EK31/A1M answers that with an external pilot oil return and internal pick-up, converting 325 l/min nominal flow at a weight of 20.2 kg.
Benefits
- 325 l/min nominal flow, 870 l/min maximum flow
- External pilot oil return, independent of back pressure in the main return
- Internal pilot oil supply, so no additional pressure line is needed
- Spool symbol W8, three switching positions, four ports
- Analogue command value ±10 V, on-board electronics, 24 VDC supply
- Operating pressure up to 350 bar, subplate mounting ISO 4401-08-08-0-05
