Electric actuators are automated devices that convert electrical energy into mechanical energy, primarily used to control the opening, closing, adjustment, and positioning of valves. Key applications include:
Industrial Process Control: In the petroleum, chemical, and power industries, electric actuators are used to precisely regulate the flow, pressure, and temperature of pipeline media. For example, in refineries, they control the opening of crude oil delivery valves with a response speed of up to 0.1 seconds and a positioning accuracy of ±0.5%.
Water Treatment Systems: These are used to control gate and butterfly valves in sewage treatment plants. They support IP68 waterproofing and can operate underwater for extended periods up to 5 meters. Typical applications include oxygen flow control in aeration tanks and are compatible with DN50-DN1200 pipes.
Building Automation: They control chilled water valves in central air conditioning systems. They support Modbus communication protocol and can be linked to building automation systems. They have an operating temperature range of -30°C to +70°C and a torque output of 20Nm-500Nm.
Energy: Gas distribution stations utilize explosion-proof actuators (Ex dⅡBT4 certified) to remotely open and close ball valves, withstanding pressures up to PN40 and capable of over 100,000 opening and closing cycles.
Special Applications: Nuclear power facilities utilize titanium alloy actuators, resistant to a radiation dose rate of 100 kGy/h and boasting a lifespan of 30 years. The food and pharmaceutical industries utilize sanitary-grade actuators with a surface roughness of Ra ≤ 0.8 μm.
