In flammable and explosive environments such as chemical, petroleum, and metallurgy industries, a large number of high-power electromechanical devices are densely deployed. When these devices frequently start and stop, or when power grid fluctuations occur, strong electromagnetic interference and transient pulses are generated. For electric actuators controlling the opening and closing of fluid valves, a lack of protection in a complex electromagnetic environment can easily lead to signal distortion, control board crashes, or even component burnout. In hazardous areas with potential flammable materials and oxygen, any uncontrolled valve node may trigger a serious explosion-proof safety crisis.
To ensure the absolute reliability of fluid automation control systems, engineering selection must strictly consider the electromagnetic compatibility (EMC) capability of the equipment. Modern high-standard explosion-proof electric actuators have introduced industrial-grade anti-interference mechanisms into their circuit designs.
Regarding electrical parameter selection, it is recommended to focus on actuators equipped with a 4kV anti-EFT interface circuit, which protects the electric actuator without interference in complex electromagnetic environments and ensures valve open-close control is reliable. Furthermore, for outdoor pipeline application scenarios, the equipment must be equipped with a strong surge protection circuit capable of resisting 1kV lightning surge waveforms, ensuring it won't be burned when used outdoors in extreme thunderstorm weather.
