Servovalves and Servo-Proportional Valves

Direct-Operated Servovalves 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 (improves operating limits), offering no flow limitations
Directly driven design means pressure-independent dynamic performance
Low current consumption at and near hydraulic null
