Direct-Operated Servo Valves with Fieldbus Interface D636 and D637 Series
ISO 4401 SIZE 03 AND 05
- Directly driven by linear force motor with no pilot flow required
- Linear force motor with high force range offering no flow limitations
- Directly driven design means pressure-independent dynamic performance
- Low current consumption at and near hydraulic null
- Integrated digital electronics allows a high grade of flexibility with fieldbus interface
