An electric actuator is an automated device in industry that drives valves or mechanical equipment through electrical energy. It converts electrical signals into linear or rotational displacements and is widely used in industrial process control systems to achieve remote, precise, and efficient control of the operating status of various equipment.
The main uses of electric actuators in industry:
1. Application areas of valve automatic control: petrochemical, water treatment, HVAC, power plants, natural gas pipelines, etc.
2. Automated production line control: Electric actuators can be used to drive equipment components to perform repetitive movements or positioning actions to improve production efficiency and automation.
3. Precision adjustment of fluid systems: Electric actuators can accurately adjust the valve opening and are used for closed-loop control of the pressure, temperature, flow, etc. of the medium.
4. Remote control and intelligent monitoring, modern electric actuators support access to:
1) PLC / DCS / SCADA system
2) Support Modbus, Profibus, Hart, 4-20mA and other protocols
3) Realize remote start and stop, status feedback, self-diagnosis, alarm and other functions
5. Explosion-proof / special environment application: In some dangerous environments (such as chemical, oil and gas industries), equipped with explosion-proof electric actuators, valves can be safely controlled without manual approach, improving safety.
