Freya SD quarter-turn electric actuators are mainly used to control quarter-turn valves such as flue shut-off doors, flow valves in cement homogenization silos, shutter valves, dampers, plug valves, and flapper valves. The new-generation upgraded model adds an independent junction box to the traditional method, which makes wiring more convenient and improves the protection ability for outdoor use. The motor has a self-locking function to prevent inertial coasting. The hand wheel is equipped with a braking device to prevent the accompanying electric operation during electric operation. The end of the output arm installed on the base is splined and can be installed at any angle.
