    How to Improve the Control Accuracy of Electric Actuator?

    Electric actuators are important devices in automatic control systems. Due to the limitation of use conditions, maintenance level and installation location, the control accuracy of electric actuators is generally about 3%, and some even exceed 5%, which seriously restricts the improvement of system adjustment quality. For fast-response control systems, it is even more important to improve the control accuracy of electric actuators. ATO various electric actuators are mainly used to control the working conditions of media such as gas, tar, steam, water, and waste gas. In production practice, according to different influencing factors, corresponding technical measures were taken, so that the control accuracy of electric actuators all reached more than 2%, and some exceeded 1.2%, which played a great role in improving the control system quality.

    How to Install Electric Valve Actuator?

    The electric actuator is an important execution unit of the combined instrument of the electric unit. It consists of two completely independent components, the control circuit and the actuator, which can receive the electric control signal from the regulator and convert it linearly into a mechanical angle or linear displacement. It can be also used to control the adjustment of the damper, baffle, valve, and other mechanism for automatic control. In recent years, with the rapid development of electronic technology and control technology, electric actuators have also achieved rapid development. Because of the powerful functions of electric actuators, they are widely used in industrial production and are purchased and installed by more and more people. So what should we pay attention to when installing? Next, let's take a look together.

    Pneumatic Valve Actuator vs. Electric Valve Actuator

    Most of the actuators used in industrial control applications today are pneumatic valve actuators, because the air source is used as power, which is more economical than electric and hydraulic, and the structure is simple, easy to master and maintain. From the point of view of maintenance, pneumatic actuators are easier to operate and calibrate than other types of actuators, and they can also be easily interchanged on the spot. Ideal for flammable and explosive environments when using positioners.
