The core function of the electromagnetic valve in Atlas Copco air compressors
The electromagnetic valve controls the valve core movement through the on-off operation of the electromagnetic coil, thereby opening or closing the pipeline and regulating the flow of compressed air, lubricating oil, or control gas. Specific applications include:
Controlling the opening and closing of the intake valve to adjust the loading/unloading state of the compressor;
Controlling the action of the relief valve to release pressure during shutdown;
Participating in the temperature control system to regulate the working state of the cooling fan or oil cooler;
Cooperating with minimum pressure valves, safety valves, etc., to ensure stable system pressure.
Types and Specifications
Depending on different models and application scenarios, Atlas Copco electromagnetic valves have various types:
According to the control medium, they can be divided into air control electromagnetic valves (for controlling compressed air) and oil control electromagnetic valves (for controlling the lubricating oil circuit);
According to the structure, they can be classified as direct-acting, pilot-operated, etc. The former is suitable for low-pressure and small-flow scenarios, while the latter can be used for high-pressure and large-flow control;
Common voltage specifications include AC220V and DC24V, matching the power supply of the compressor control system.
Design and Material Characteristics
The valve body is mostly made of corrosion-resistant metal materials (such as brass, stainless steel), adapting to the oil and gas environment inside the compressor and ensuring structural strength and sealing performance;
The valve core and sealing components are made of wear-resistant and oil-resistant materials (such as engineering plastics, fluororubber), reducing wear and leakage risks and prolonging service life;
The coil part is encapsulated with high-temperature-resistant insulating materials, adapting to the temperature changes in the compressor working environment and ensuring electrical safety.
Original Equipment Advantages
Precise Adaptation: The parameters of the original factory electromagnetic valves (such as diameter, pressure rating, response speed) are fully matched with the control system of specific models, ensuring precise and reliable operation, and avoiding control failure due to compatibility issues;
Strong Stability: After rigorous durability tests, they can maintain long-term stable operation under frequent on-off conditions, reducing fault shutdowns;
System Coordination: They work in coordination with the PLC control system, sensors, etc. of the compressor to ensure the smooth execution of the overall control logic.
