Rotork Electric Actuator Description: Promethean Tech has developed proficiency in the installation of electric actuators, encompassing bush fabrication, cabling tasks, and testing and commissioning.. Actuators consist of a motor driving onto a worm gearbox which provides the output torque required to move a valve. In short, they’re electronically powered devices that convert a control signal into a rotary or linear movement which, via a valve unit, changes the flow of a fluid.
