Servo Valve an overview ScienceDirect Topics

Servo valves are a close relative of the proportional valve and are based on an electrical torque motor which produces a small deflection proportional to the electrical current through its coil.monly use feedback between the main and pilot spools to give precise control. A typical device is shown in Figure 4.40.This consists of a small pilot spool connected directly to the torque motor.

Servo valve HAWE North America

The servo valve and its qualities largely determine the behaviour of the drive. That is particularly true in terms of its dynamic properties. Therefore, frequencies over 150 Hz can be expected from a servo valve today at a damping of 0.6. However, that can only be achieved with extremely short control distances of a few tenths of millimetres.
