Special Valves
![[Mounting Pattern NG 6]](http://s2.servo-hydraulik.de/i/sks-stage-ng6.jpg)
The servovalve range embraces single, two and three-stage valves in a flow rate range from 0.4 to 1000 l/min. Besides the standard range, application-related valve series are available, e.g.:
- special characteristics,
- low-leakage pistons,
- two return flanges or
- highly dynamic valves
