World"s Fastest! Next-Generation Linear Servo Valve High Speed Linear Servo Valve Series

  • Feature1:High Response

    A compact, powerful linear motor ensures maximum response for a servo valve.
  • Feature2:High Precision

    Yuken's electronics technologies and closed loop control achieve hysteresis of 0.1% or less.
  • Feature3:Exceptional contamination resistance

    Direct drive spool (with a pilot valve for 2-step models) ensures exceptional NAS10-class contamination resistance.
  • Feature4:Convenient

    The OBE type valves feature a display light distinct from regular alarm output. This allows visual confirmation of current flow and failure diagnostics.
