Product Introduction	There are three types of actuators used in regulating valves: pneumatic, electric, and hydraulic (electro-hydraulic), each with its own advantages and disadvantages in terms of performance. They are described below. 1. Pneumatic actuator: Most industrial control applications nowadays use pneumatic actuators because they are powered by air sources. Compared to electric and hydraulic actuators, they are more economical and have a simple structure, making them easy to master and maintain. From a maintenance perspective, pneumatic actuators are easier to operate and calibrate than other types of actuators, and can also be easily interchanged on site. Its biggest advantage is safety. When using a locator, it is ideal for flammable and explosive environments. However, if the electrical signal is not explosion-proof or inherently safe, there is a potential risk of fire caused by ignition. So the application range of electric control valves is becoming increasingly wide. However, in the chemical industry, pneumatic control valves still hold an absolute market advantage. The main drawbacks of pneumatic actuators are slow response, poor control accuracy, and poor resistance to deviation. This is due to the compressibility of gas, especially when using large pneumatic actuators, which require time for air to fill and empty the cylinder. But this should not be a problem, as many working conditions do not require high control accuracy, extremely fast response, and anti deviation ability. 2. Electric actuators: Electric actuators are mainly used in power plants or nuclear power plants because a smooth, stable, and slow process is required in high-pressure water systems. 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, and only hydraulic actuators can achieve such a large thrust. However, 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 (keep/fully open/fully closed). However, in case of a fault, it must remain in its original position, which cannot be achieved by pneumatic actuators. Pneumatic actuators must rely on a combination protection system to achieve position retention. The main drawbacks of electric actuators are: their structure is more complex, making them more prone to malfunctions, and due to their complexity, the technical requirements for on-site maintenance personnel are relatively higher; The operation of the motor needs to generate heat. If adjusted too frequently, it can easily cause the motor to overheat, generate thermal protection, and also increase wear on the reduction gear; In addition, it runs slowly, taking a longer time from the regulator outputting a signal to the regulating valve responding and moving to the corresponding position, which is why it is inferior to pneumatic and hydraulic actuators. 3. Hydraulic actuator: When abnormal resistance to deviation, high thrust, and fast formation speed are required, we often choose hydraulic or electro-hydraulic actuators. Due to the incompressibility of liquids, the advantage of using hydraulic actuators is their superior resistance to deviation, which is important for regulating operating conditions. When the regulating element approaches the valve seat, the throttling condition is unstable, and the greater the pressure difference, the more severe this situation becomes. In addition, the hydraulic actuator runs very smoothly and responds quickly, so it can achieve high-precision control. The electro-hydraulic actuator integrates the motor, oil pump, and electro-hydraulic servo valve into one, and can work as long as the power supply and control signal are connected. The hydraulic actuator is similar to the cylinder, but can withstand higher pressure than the cylinder. Its operation requires an external hydraulic system, and the factory needs to be equipped with a hydraulic station and oil pipeline. In comparison, the electro-hydraulic actuator is more convenient. The main drawbacks of hydraulic actuators are their high cost, bulky and complex physical examinations, and the need for specialized engineering. Therefore, most of them are used in special situations such as power plants and petrochemicals.
