◆ Advantages

The main advantage of electric actuators is their high stability and the constant thrust that users can apply. The maximum thrust generated by the largest actuator can reach up to 225,000 KGF. Only hydraulic actuators can achieve such a large thrust, but the cost of hydraulic actuators is much higher than that of electric ones.

The anti-deviation capability of electric actuators is excellent. The output thrust or torque is basically constant, which can effectively overcome the unbalanced force of the medium and achieve accurate control of process parameters. Therefore, the control accuracy is higher than that of pneumatic actuators. If a servo amplifier is used, it is very easy to switch between positive and negative actions, and the valve position state (hold/fully open/fully closed) can also be easily set when the signal is off. In case of a fault, it will definitely remain in its original position, which is something that pneumatic actuators cannot do. Pneumatic actuators must rely on a set of combined protection systems to achieve position retention.
