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.
