The core features and applications of the electromagnetic valves of Atlas Copco industrial compressors are as follows:
Function and Classification:
Intake Valve Control Electromagnetic Valve: Controls the opening and closing of the intake valve through on-off control, adjusting the load/unloading state of the compressor, and directly affecting the exhaust volume and energy consumption.
Sewage Electromagnetic Valve: Opens at regular intervals to discharge the condensed water and oil sludge separated by the compressor, preventing the accumulation of impurities that may affect the quality of the compressed air.
Pressure Control Electromagnetic Valve: Cooperates with the pressure sensor to trigger the unloading or shutdown action when the set pressure is reached, ensuring stable system pressure.
Other Auxiliary Electromagnetic Valves: Such as dedicated electromagnetic valves for controlling the minimum pressure valve, servo cylinders, etc.
Technical Characteristics:
Voltage Specifications: Commonly used AC voltages include 110V, 220V, etc., and DC voltages are mostly 24V. They need to be matched with the electrical system of the compressor (frequencies are usually 50Hz or 60Hz).
Material and Temperature Resistance: The valve body is mostly made of brass or stainless steel, and the sealing parts use oil-resistant rubber (such as nitrile rubber), which can adapt to the oil and gas environment inside the compressor and the working temperature is generally -10℃ to 80℃.
Response Speed: Designed as a fast-response type, ensuring that the on-off switching is completed within milliseconds, guaranteeing control accuracy.
