• Internal position feedback corrects spool deviation on its own
• Command value ±10 V processed directly by the on-board electronics
• External pilot oil supply with internal return, V spool
• Operating pressure 350 bar, three switching positions, four ports
• Weight 18 kg on port pattern ISO 4401-08-08-0-05
