Electric actuators are widely used in industrial automation control systems, where their primary function is to precisely regulate or switch valves, dampers, and other equipment via electric power. Below are their key application scenarios and typical industries.
I. Applications by Motion Type
-
Quarter-Turn (Rotary) Actuators
- Used for butterfly valves, ball valves, and other rotary valves.
- Typical Applications:
- Oil & Gas/Petrochemicals: Controlling corrosive media pipelines (e.g., acid/alkali storage tank inlets/outlets).
- Water Treatment: Adjusting pH dosing lines in wastewater plants.
- HVAC: Regulating temperature via dampers or butterfly valves.
-
Linear (Straight-Line) Actuators
- Used for globe valves, gate valves, and other linear-motion valves.
- Typical Applications:
- Power Industry: Pressure regulation in boiler feedwater systems.
- Food Processing: Precise flow control in sterile production lines.
- Automotive Manufacturing: Linear positioning in welding and painting processes.
-
Multi-Turn Actuators
- Used for gate valves and globe valves requiring multiple rotations.
- Typical Applications:
- Municipal Engineering: Remote on/off control of pump stations and sewer systems.
- Energy Sector: Isolation control in high-pressure pipelines at power plants.
-
II. Industry-Specific Applications
-
Chemical & Petrochemical Industry
- Control of highly corrosive media (e.g., sulfuric acid, hydrochloric acid pipelines).
- Automated regulation of reactor fluid transfer.
- Safety control in explosive environments (Ex-certified required).
-
New Energy Industry
- High-purity control of lithium battery electrolyte transfer.
- Valve control in trichlorosilane purification for photovoltaic silicon production.
-
Pharmaceutical & Food Industry
- Hygienic valve control in sterile drug production (FDA/GMP certified).
- Contamination-free adjustment of fermentation tank medium transfer.
-
Construction Machinery & Municipal Vehicles
- Automatic throttle control in excavators.
- Hydraulic system replacement for garbage truck dumpers.
- Quick-attachment systems for loaders.
-
III. Special Environment Applications
- Outdoor Use: IP55/IP65-rated actuators for pump stations and pipelines.
- High-Precision Control: Micro-flow adjustment (e.g., chemical dosing in water treatment).
- Remote Control: Integration with DCS systems for automated production lines.
