Features of Micro Gas Solenoid Valve:
● Small size and light weight
Very suitable for integrated devices in compact spaces, easy to install in portable or micro systems.
● High air tightness design
Specially optimized for gas control, with excellent sealing performance and strong anti-leakage ability, especially suitable for precision gas analysis or control.
● Fast response time (millisecond level)
Quick opening/closing, suitable for high-frequency switching control.
● Low power consumption, suitable for battery-powered systems
Common voltages are 3V, 5V, 12V, and 24V, supporting continuous operation or pulse drive.
● Precise flow control
Can adjust small flow rates of gas, such as 0.1 to 10 L/min, suitable for precision control systems.
● Long service life
High-quality electromagnetic coils and seals can guarantee millions of switching cycles.
● Various materials, suitable for a variety of gases
The valve body is often made of stainless steel, PBT, PTFE, etc., suitable for a variety of inert or non-corrosive gases such as air, nitrogen, oxygen, CO₂, etc.
Typical applications of micro gas solenoid valves:
1. Medical equipment
● Ventilators, anesthesia machines, oxygen generators, nebulizers
● Control the flow and on-off of gases (such as oxygen, air, nitrous oxide)
2. Gas analysis and environmental monitoring
● Gas detectors, CEMS, mass spectrometers, chromatographs
● Quickly switch or quantitatively control the flow of gas samples into the detection system
3. Laboratory automation and microfluidics systems
● Gas path switching, gas mixing systems
● Automatic, multi-channel gas control
4. Industrial control and automation
● Micro pneumatic devices, precision dispensing, laser gas cooling systems
● Precisely control gas switches or drive other pneumatic components
5. Consumer electronics and smart homes
● Smart toilet deodorization system, odor release system, small air pump supporting control
● Control small gas volume on and off or timed release of gas
6. Automobiles and new energy
● Fuel cell systems, cabin air management systems
● Control the flow of hydrogen, oxygen, etc. in energy or vehicle systems
