While linear EMAs can replace hydraulic systems, they can also be converted to rotary EMAs for added benefits. Rotary EMAs are more compact, efficient, and easily maintained than linear actuators.
Electric actuators based on servo-motor and roller-screw technologies can enable a responsive and accurate electric actuator solution that‘s well suited for valve control
Using a GSX servo actuator with its integrated roller screw and motor, Colpitt was able to achieve a quick transfer motion combined with a controlled low speed move, pressing at the end of each move.
