Amplifier Valves

Operating principle
The electro-hydraulic amplifier is a compact drive with mechanical position feedback. The 3 main sets are:

1.) Set-value input Rotary set-value input with smallest power provided by any mechanical means electric servo motors.

2.) Control valve The control valve is a 4-edge valve. The 4 valve inserts can be selected and set independendly and can be adjusted to the given section relations and to the spring-mass-systems to be moved

3.) Power amplifier Hydro-cylinders, -motors and part-turn actuators can be used as drive. The three main sets forming a closed loop are in direct active connection with the parts to be connected to by means of the spindle or rack/pinion feedback system.
