The main defect of the electric actuator for valves in Yangzhou is its relatively complex structure, which makes it more prone to malfunction. Moreover, due to its complexity, the skill requirements for on-site protection personnel are relatively higher. The motor operation generates heat. If the adjustment is too frequent, it is easy to cause the motor to overheat and trigger thermal protection. At the same time, it will also increase the wear of the reduction gears. Another issue is that it operates relatively slowly. From the time the regulator outputs a signal to the time the regulating valve responds and moves to the corresponding position, it takes a long time. This is where it lags behind pneumatic and hydraulic actuators.
The electric actuator of Yangzhou valve features a high degree of stability and a stable thrust that users can apply. The thrust generated by the actuator can reach up to 225,000 KGF. Only the hydraulic actuator can achieve such a large thrust, but the cost of the hydraulic actuator is much higher than that of the electric one. The anti-deviation capability of electric actuators is excellent. The output thrust or torque is basically stable, 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, the exchange of forward and reverse actions can be easily accomplished, and the valve position status when the signal is disconnected can also be easily set. However, when a fault occurs, it will definitely remain in its original position, which is something that pneumatic actuators cannot do. Therefore, pneumatic actuators need to rely on a set of combined protection systems to achieve protection.
The above is a brief description of the advantages and disadvantages of the electric valve actuator in Yangzhou. We hope that after reading this article, you can try to avoid these misunderstandings.
