Hydraulic valve actuator
Eckart
No radial forces have an effect on the shaft of the fitting.
This saves as well as the bearing and the packet
With the hollow shaft design or an adapter hub the required
Eckart rotary actuator can adapted to every Zwick high performance flap
Very fast control times (e.g. 90° in 0.2 seconds) can be realized
By the optimal end cushioning of the Eckart rotary actuator the
closing stop position of the fitting is also saved
The regulation of the volume flows is very simple and repeating exact
No additional lubrication is necessary
