AT RANGE

The multi-turn applications will soon be addressed with the AT range. These new products are even more closer to standard actuation needs in the power, water or various industry applications than the previous FIRST BC generation. This new AT range guarantees the essential functions required to operate a valve or a damper in moderate environmental and operational constraints.
