Linear actuators combinations SA ... LE, ALS

To perfom linear movements, e. g. in case of globe valves, the multi-turn actuator SA ... can be combined with the linear thrust unit LE, forming an electric linear actuator. In case a lever arrangement has to be operated, the linear thrust unit can be mounted on a base.

For reasons of safety, a fail-safe function is required of the actuator.  In case of a power failure the valve has to be opened or closed by spring action. The linear actuator ALS meets this requirement.
