Total price
While levelling, the roll setting moves constantly in small steps as the strip is pulled through at full force. The 4WRZE25E1-220-7X/6EG24N9TK31/A1D3M provides 220 l/min nominal flow for that, commanded by ±10 V and fed by an external pilot supply.
Benefits
- A ±10 V command value allows fine correction steps straight from the axis controller.
- External pilot supply with internal return saves a line compared with the fully external version.
- Nominal flow 220 l/min at 350 bar operating pressure, plant maximum 870 l/min.
- Spool symbol E1, 3 switching positions, ISO 4401-08-08-0-05, 4 ports, 20.58 kg.
- On-board electronics at 24 V DC, concealed manual override, UKCA to SI2016/1091.
