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.

2010.7.14 All servo valves are flow rated at 1,000 psi (7 MPa according to ISO 10770-1, which converts to about 1,015 psi) and have been for several decades. The rated flow of a servo valve is that flow which is measured with 1,000 psi differential pressure from the pressure port to the tank port while the work ports are looped. On the other hand ...

2023.7.25 Fig. 5.11 Servo Valve (Flapper-Nozzle Type) A very small electrical current (flow rate set-point) applied to the torque motor coils creates a magnetic force. This force swings the armature/flapper assembly to one side, restricting the fluid flow from one of the two nozzles (Fig. 5.11). This restriction of fluid quickly builds pressure on one ...

2021.3.3 A servo valve can vary the fluid flow according to the changes in the load motion. Servo valves can control high power by using small inputs and it could be electrical or mechanical. So basically a servo valve is a directional control valve, this valve can control the flow and also the direction of the flow.
