Direct-Operated Servo Valves for Analog Signals D636 and D637 Series
- 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
