Parker BD Series Servo Valve
Parker BD Series Servo Valve

Series BD servovalves provide high resolution in the control of position, velocity and force in motion control applications.

Features

  • Rugged reliable trouble-free operation.
  • Reduced contaminant sensitivity.
  • Linear flow gain characteristics.
  • Intrinsically safe model available.
  • Explosion proof model available.

Operation

When used in conjunction with Series BD90 and BD101 servo amplifiers or a motion controller, Series BD valves will provide accurate control of rotary and linear actuators.
