[YUKEN] — LSVG-03 Direct Type High-Speed Linear Servo Valve
Family ID: YK-LSVG03
Direct type high-speed linear servo valve using a compact, powerful linear motor as the actuator, with the moving coil, spool, and position sensor combined in series for a very simple structure. Hysteresis 0.1% or less; step response 2 ms (size 60: 3 ms); frequency response −3 dB gain up to 350 Hz. Excellent vibration resistance from the simple construction and superior contamination tolerance, usable to NAS 1638 class 10 (ISO4406 21/19/15). Max operating pressure 35 MPa. Neutral zero-lap spool. Requires dedicated AMLS linear servo amplifier.
