Actuator technology is changing fast and most manufacturers are endeavoring to cut down on costs of studies and produce products in series. It can be said that actuators govern the action faculties of “muscles” in applications. Depending on the area, actuators are considered to be slow, semi-fast, fast or otherwise control influx: flow, action, pressure, power, strenght. There is a large family of actuators but it is indeed incomplete for many years because many applications require fast actuators capable of using relatively high flows and pressure levels at acceptable costs. For instance, flows ranging from 0,16 to 0,5 dm3/s, pressures of 100 to 300 × 105 Pa on pressure loads of 20 Hz to 30 Hz bandwidth. Today, the main clients are users of aircraft and automobile brakes and other industrial areas. This article is aimed at provided professionals with information about fast acting actuator technology in the form a new multipurpose servo valve for fast applications.
