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. The actuator can be set up and programmed directly at the installation site and is very easy to do, 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 a fail-safe spring return function that closes the valve when power is interrupted. Type SF is additionally equipped with two auxiliary switches that activate at rotation angles of 5° and 85°. 

When using the product outdoors, a canopy against external influences is required.
