Main types and functions:
The functions of the electromagnetic valves in different series of air compressors vary. Common types include:
Loading / Unloading Electromagnetic Valve: Controls the opening and closing of the intake valve to achieve the switching between the loading (gas production) and unloading (idle operation) states of the air compressor;
Drainage Electromagnetic Valve: Works in conjunction with the electronic drainage valve, opening at regular intervals to discharge condensate water without the need for manual operation;
Safety Electromagnetic Valve: Receives signals from the controller in emergency situations (such as overheating, overpressure) and quickly cuts off the intake or stops the main unit operation;
Servo Electromagnetic Valve: Works in conjunction with the proportional regulating valve to precisely control the intake volume, meeting the stepless adjustment requirements of variable frequency models.
Core advantages of original accessories:
The original factory electromagnetic valves have the following characteristics:
High reliability: Use high-quality coils and sealing materials, with a service life of over 100,000 times, capable of withstanding the vibration of the air compressor, high temperatures (environmental temperature -10 to 60℃), and oil contamination;
Quick response: The valve opens within ≤0.1 seconds after power-on, ensuring the rapid execution of control instructions;
Precise fit: Voltage specifications (such as 24V DC, 110V AC, 220V AC) match the air compressor control system, and interface dimensions (threads or quick-connect) are fully compatible with the pipelines;
Low power consumption design: The coil power is small (usually 5-15W), reducing energy consumption while lowering heat generation.
Key points for model matching:
The selection of the electromagnetic valve needs to match the following parameters:
Air compressor model (such as GA11, GA37VSD+ ) and control system type (such as Elektronikon IV);
The purpose of the electromagnetic valve (loading control, drainage, safety protection, etc.) and installation location;
Working voltage, interface dimensions (such as G1/4, G3/8), and the old valve part number (usually marked on the valve body).
For example, the loading electromagnetic valve of the GA series small-power models and the safety electromagnetic valve of the ZR series oil-free machines have significant differences, requiring precise matching.
