Servo Directional...

Servo Directional Control Valves

Function:

Very accurately control the flow into the A or B lines depending on the electrical control signal. Generally used in high performance closed loop control systems.


Setting:

Servo valves require a significant pressure drop across the valve to accurately control the flow, say 30 bar, and stiff, high natural frequency, systems to operate correctly.


Require very good fluid cleanliness


Variations:

Spool center positions bias may vary.


Valve response times may vary.
