• Resumen

  • The use of electrohydraulic systems is becoming more widespread in industry. The control valve forms a vital component of any such system as it performs both power conversion and amplification. The valve is operated by a solenoid mounted on the end of the valve block. A typical solenoid actuator is shown in Fig. 1. Current through the coil generates a magnetic potential difference across the air‐gap, producing an attractive force between the opposing pole face and armature. The armature moves to close the air‐gap and minimize the reluctance of the magnetic circuit.
