Solenoid valve CO2 2 W, sera SE-08030, electromagnetic valve for aquarium CO2 systems

The sera solenoid valve CO2 2 W (model SE-08030) is an electromagnetic shut-off valve designed for low-pressure CO2 lines in aquariums and small-scale plant cultivation systems. Compact and electrically actuated, it provides automated on/off control of CO2 flow for timed dosing, safety shutoff and simple integration with timers or controllers. The valve is intended for inline installation and operation at the low pressures typical of aquarium CO2 regulators and tubing systems.

Advantages

This electromagnetic valve consumes 2 W of power and offers quick response for reliable switching of CO2 supply. Its compact construction allows installation in confined spaces near the regulator or along the tubing run. Electrical actuation enables straightforward connection to mechanical timers or electronic controllers for automated day/night dosing or emergency shutoff. The design focuses on ease of integration, consistent operation and compatibility with common aquarium CO2 setups.

Suitable for

• Automated CO2 dosing in planted aquariums
• Integration with timers or aquarium controllers for day/night CO2 schedules
• Inline safety shutoff in low-pressure CO2 tubing systems
• Small-scale plant cultivation setups using regulator-based CO2 supply

When it may not be suitable

This valve is intended for low-pressure CO2 systems typical of aquarium regulators; it may not be appropriate for high-pressure cylinders or direct connection to compressed gas sources without a suitable pressure regulator. It is designed for CO2 gas applications—use with liquids, other gases, or at pressures outside the valve’s intended range is not recommended.

Key specifications

• Actuation: electromagnetic solenoid
• Power consumption: 2 W
• Application: low-pressure CO2 lines for aquariums and plant cultivation
• Installation: inline mounting in tubing runs
• Control: on/off switching compatible with timers and controllers

How to use

Install the valve inline between the CO2 regulator and the aquarium tubing, ensuring correct flow direction where indicated. Connect the electrical leads to a suitable 2 W-capable timer or controller following the controller’s wiring instructions and local electrical safety rules. Test the assembly at low pressure to confirm leak-free connections, then verify the valve opens and closes correctly under timed or manual control. Regularly inspect fittings and tubing for wear and replace any components that show degradation.

What to consider before purchase

• Confirm your CO2 system uses low-pressure tubing and a compatible regulator
• Ensure you have a timer or controller capable of driving a 2 W solenoid
• Check physical space for inline installation near the regulator or tubing run
• Plan for safe electrical connection following local regulations

Usage recommendations

For reliable operation, mount the valve where it is protected from splash and excessive humidity, use thread sealant or appropriate fittings to prevent leaks, and operate the solenoid within the rated pressure and power limits. Pair the valve with a quality pressure regulator and bubble counter or diffuser to ensure accurate CO2 dosing for planted tanks.
