Benefits
- Command value 4...20 mA for very long signal runs, a broken wire shows as zero current
- External pilot oil supply and return for a separately fed pilot circuit
- Nominal flow 350 l/min, up to 870 l/min through the valve at 350 bar
- Internal spool position feedback, V1 spool
- On-board electronics with a 7-pole (6 + PE) connector to EN 175201-804
- Weight 18.06 kg, port pattern ISO 4401-08-08-0-05
