Advantages of electric actuators

The main advantages of electric actuators are high stability and constant thrust that users can apply. The maximum thrust generated by the actuator can reach up to 225000kgf. Only hydraulic actuators can achieve such a large thrust, but the cost of hydraulic actuators is much higher than that of electric actuators.
The anti deviation ability of electric actuators is very good, and 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 equipped with a servo amplifier, it is easy to achieve the exchange of positive and negative effects, and it is also possible to easily set the cut-off signal valve position state (maintain/fully open/fully closed). When a fault occurs, it must remain in its original position, which cannot be achieved by the pneumatic actuator. The pneumatic actuator must rely on a combination protection system to achieve position protection.
