Features & Benefits
Easy commissioning
Automatic measurement and adaptation to the valve lift as well as load-dependent end position switch-off helps to reduce commissioning time and protect the valve and actuator from overloading.
Easy troubleshooting
Protected hand drive for a safe manual operation which enables easy troubleshooting.
Ease of service
The actuator housing cover is easy to remove. Parameters can easily be changed on site.
