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.
