Blow moulding machines cycle fast and leave little room in the manifold for extra lines. The 4WRZE10W8-85-7X/6EG24N9ETK31/A1M therefore routes pilot oil supply and return internally, regulates 85 l/min nominal flow through spool symbol W8 and accepts an analog ±10 V command value.
Benefits
- Internal pilot oil supply and internal return, no extra drillings in the manifold.
- Spool symbol W8 with 85 l/min nominal flow, maximum flow 170 l/min.
- Analog ±10 V command value on on-board electronics, 24 VDC supply.
- Version without pressure reducing valve, concealed auxiliary actuation fitted.
- Operating pressure up to 315 bar, size 10, weight 7.95 kg.
