Modern production control system, most of the use of electric actuator valve actuator, it is relatively traditional valve control device to use more safe, more simple institutions, the service life is stronger. Electric valve head can be basically divided into two parts, the part is the electric control part, lower part is the main part of the valve, electric actuator applications are widely for various operational conditions adaptability is very high, so by the majority of users love, has been when as an intelligent valve control device.
When the electric actuator in the practical application of the operation process we users to spend three stages. The first is the run in the running period. Most of the faults occurred during the selection, design or installation and environment caused by. For example when the torque is too small may directly affect the speed of the electric valve actuator. If the installation of power lines and signal lines to stir together, it will cause a large signal interference, the stability of the motor operation. Encountered these problems must be found and processed in a timely manner, so as to avoid unnecessary losses. When the valve electric head into the operation, the overall performance of the control mechanism has also entered the adaptation period most of the performance is relatively stable, there will be a small problem of individual failure, the user can only do a proper maintenance. And when the valve electric actuator into the late operation, most of the existing mechanical component aging, especially various transmission parts wear serious problem, result to the decrease of control operation stability, or intelligent locator module positioning accuracy decline. Users should find out the reasons for these problems through repair or replacement parts to get better solution.
Electric actuator has become the mainstream products in the market. Automatic valve in the most can not be missing is the electric actuator, the work can be effective in saving energy consumption. The advantages of the electric actuator performance determines whether the use of the time can effectively improve work efficiency and energy saving. There are various types of motor, in the market, there are different types of electric head, such as angular travel. The most commonly used electric head is the most traditional electric head. In more advanced Rotork electric actuator compared to traditional electric actuator is inferior to a lot, but does not affect the market of the traditional electric actuator.

The traditional electric actuator also has the advantage. The use of energy on the more convenient, just plug in the power can be carried out. When the transmission signal is relatively fast, and can transmit a long distance. In long-distance transmission control and will not be affected, in the control of the time still has a strong precision, not because the distance is too far to be unable to control. The installation of visual wiring process is relatively simple, not cumbersome. When a fault occurs, you can quickly check the fault point, when the line is able to quickly replace the problem of the line to replace the new line. Maintenance is relatively simple, no need to consume a large amount of maintenance costs.
The disadvantage of the electric actuator is that the structure is more complicated, so it is easy to be trouble. Because the structure is more complex, need to have a strong professional knowledge and technical high maintenance personnel. Failure in the electric actuator is able to quickly solve the fault, professional knowledge and technology is not high maintenance personnel in the maintenance time will consume a lot of time. Reduces the working time, reduces the work efficiency.
The most widely used definition of an actuator is that it can provide a linear or rotary motion drive, which uses a certain type of drive energy and works under a control signal. The actuator uses liquid, gas, electricity or other energy sources and is converted into a driving force by a motor, cylinder or other device.
