An electric actuator designed for safety and shut-off dampers, ball valves, butterfly valves, VAV systems, and other applications requiring motorized control. It is suitable for use in the chemical and pharmaceutical industries and on oil platforms or refineries in EEx environments (ATEX zones 2, 22).

The actuator is built to withstand the most challenging conditions. Its small size and low weight allow for easy installation, and the IP66 enclosure protects the actuator from adverse external influences. The actuator can be set up and programmed directly on-site, and it is very easy to do so as it requires no additional equipment or tools.

A particularly handy feature is the self-adaptive motor adjustment, which allows it to be powered by any voltage in the range of 24...240 VAC. The actuators are protected against overload and feature a fail-safe spring return function that closes the valve in the event of a power failure. The SF type is additionally equipped with two auxiliary switches that activate at rotation angles of 5° and 85°.

When using the product outdoors, a canopy should be used to protect against external influences.
