Placing booms and long boom axes need an unpressurised pilot oil return because the line back to tank is long and builds up back pressure. The 4WRZE10E1-85-7X/6EG24N9EK31/F1M therefore routes the pilot oil return outside, taps pilot oil internally and regulates 85 l/min nominal flow through spool symbol E1.
Benefits
- Internal pilot oil supply with external pilot oil return for a pilot stage free of back pressure.
- Spool symbol E1, 85 l/min nominal flow, maximum flow 170 l/min.
- Operating pressure up to 315 bar across four ports to ISO 4401-05-05-0-05.
- Version without pressure reducing valve, with concealed auxiliary actuation.
- Command value 4...20 mA, 24 VDC supply, weight 8.66 kg.
