Proportional hydraulics is a state of the art technology. This technology combines the hydraulic transfer of force with the precision and flexibility of electronic control.
Proportional hydraulics has bridged the gap between simple on-off ..standard" hydraulics and
servo hydraulics.
Proportional hydraulics offers power and flexibility.
The simple construction (designed for ..standard" hydraulics), together with the electronic
amplifiers (not prone to failure) causes this technology to be very popular. New machines (series and special) have been designed.
The realisation of the possibilities of proportional hydraulics is the basis of sucessful plans for
modem, hydraulically driven machines. As some proportional hydraulics is already present in
many production machines (in nearly all applications of hydraulic drives, open and closed loop control), the importance of understanding this technology is becoming Increasingly evident.
