72 Series Servo Valves

Direct-Operated Flow Control for Analog Signals

 

  • 2-stage flow control Mechanical Feedback (MFB) Valve
  • Low friction double nozzle pilot stage for high dynamics, high resolution and low hysteresis
  • High spool driving forces, rugged design ensures long-life operation
  • Dry torque notor
  • Optional 5th port for separate pilot supply
  • Field-replaceable first stage disc filter for easier maintenance
