The electromagnetic torque motors are widely used in electrohydraulic servovalves. They serve to convert the control current into a proportional torque. For more details about this issue, please refer to my book:M Galal Rabie, Fluid Power Engineering, McGraw-Hill, NY, May 18, 2009, pp 336-340This...

Hydraulic servo actuators (HSAs) are used to precisely control displacement in a wide range of equipment. Generally, a hydraulic servo actuator consists of a hydraulic actuator controlled by a directional control valve of an infinite number of positions and equipped with a feedback arrangement....
