Introduction to the main use advantages of the electric actuator

Now more and more factories adopt automatic control, manual operation were replaced by a mechanical or automation equipment, the control system and the valve actuator will be the interface between the mechanical movement, more actuators to enhance work safety and environmental protection performance, the use of the existence of the electric actuator is to have a lot of advantages, in some dangerous situations, automation of the actuator device can reduce the damage.

The main advantages of electric actuators are high stability and constant thrust, which users can apply. The maximum thrust generated by the actuator can be up to 225000 KGF. Only hydraulic actuators can achieve such a large thrust, but the cost of hydraulic actuators is much higher than that of electric actuators. The electric actuator has good anti-deflection capability. The output thrust or torque is basically unchanged. It overcomes the unbalanced force of the medium and realizes the accurate control of the process parameters, which is higher than the pneumatic actuator. If you use a servo amplifier, you can easily switch back and forth, and you can easily set the position state of the shutoff valve (maintenance/full open/full closed). If a failure occurs, it must remain in its original position. This is not possible for pneumatic actuators. Pneumatic actuators must be maintained by a combined protection system. The main advantage of this actuator is that all parts are installed in a single housing, which integrates all basic and advanced functions in a waterproof, dustproof and explosion-proof housing. The main disadvantage is that when there is a power failure, the valve can only be kept in a certain position. Only by using the standby power system can the safe position of failure be reached (failure occurs or shut down).
