How Does A Hydraulic Servo Valve Work?

A hydraulic servo valve is a precision control valve used in hydraulic systems to accurately regulate the flow and direction of hydraulic fluid. It operates by converting an electrical signal into a hydraulic output, allowing for precise control and positioning of hydraulic actuators. Here’s how a hydraulic servo valve works:

1. Valve Construction:
   • A hydraulic servo valve consists of a valve body, a spool or poppet mechanism, and electrical connections.
   • The valve body contains inlet and outlet ports for hydraulic fluid, while the spool or poppet controls the flow of fluid through the valve.
2. Electrical Input:
   • An electrical input signal, typically from a control system or a feedback device, is sent to the servo valve.
   • This electrical signal represents the desired position or level of control for the hydraulic actuator.
3. Pilot Stage:
   • The electrical input signal is received by the pilot stage of the servo valve.
   • The pilot stage typically consists of a small solenoid valve or a torque motor that receives and converts the electrical signal into a mechanical force.
4. Spool or Poppet Movement:
   • The mechanical force generated by the pilot stage moves the spool or poppet inside the valve body.
   • The movement of the spool or poppet controls the size and position of the flow passages, regulating the flow of hydraulic fluid.
5. Hydraulic Output:
   • As the spool or poppet moves, it allows hydraulic fluid to flow through the valve, directing it to the appropriate hydraulic actuator.
   • The flow of fluid to the actuator causes it to move, achieving the desired position or control as determined by the electrical input signal.
6. Feedback System:
   • In some servo valve systems, a feedback mechanism is employed to provide information about the actual position or status of the actuator.
   • This feedback is used to compare with the desired position, allowing for continuous adjustment and accurate control.
7. Control Loop:
   • The servo valve operates in a closed-loop control system, where the feedback information is continuously compared to the desired input signal.
   • Any deviation between the actual and desired positions is corrected by adjusting the servo valve’s spool or poppet position.
8. Application Examples:
   • Hydraulic servo valves are commonly used in applications that require precise control, such as robotics, aerospace systems, industrial machinery, and flight simulators.
