In practice
What is a flow control valve?
Flow control valves are used in pneumatic systems to regulate the flow rate of compressed air. By controlling the flow rate, the speed of the pneumatic cylinder can also be regulated directly. In addition, a good throttling valve contributes to reducing wear due to a lower kinetic load. Moreover, the control valves also support a more steady and thus reliable movement. The latter has to do with the fact that if the speed is unthrottled, the velocity can fluctuate. This in turn can lead to a stick/slip effect and thus to a faltering motion.
