AB-serie - semi-rotary actuators

The semi-rotary actuators for 120° consist of a combination from a rotary actuator of the AB-Series with a semi rotary geargox and are available for on off duty AB or modulating duty rAB.
In standard or explosion proof version.

For positioning elements travelling less than one revolution (e.g. butterfly valves, ball valves and similar devices)

As a standard model the on off actuator can be used for S2-15min and the modulating actuator for S4-1200c/h-40%ED.
The explosion proof model has a protection class of EExdeIICT4 acc. EN 60079 ff.
