Electric actuator designed for safety and shut-off dampers, ball valves, butterfly valves, VAV systems, and other applications requiring motorized control. It finds application in the chemical and pharmaceutical industries and on oil platforms or refineries in EEx environments (ATEX zones 1, 2, 21, 22).

The actuator is constructed to withstand the most challenging conditions. Its small size and low weight allow for easy installation, and the IP66 protection shields the actuator from adverse external influences. Setting and programming the actuator can be done directly at the installation site and is very straightforward, as it requires no additional equipment or tools.

The self-adaptive motor adjustment is very handy, allowing it to be powered by any voltage in the range of 24...230 VAC. The actuators are protected against overload and feature an emergency 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.
