Clscea Aquarium CO2 Solenoid Valve, Mini 12V DC Low-Temperature Inline Model

Clscea’s mini inline CO2 solenoid valve controls CO2 flow in an aquarium system, with 12V DC, 0.8W operation and connections for 4 mm inner-diameter, 6 mm outer-diameter tubing.

• 12V DC, 0.8W operation — designed as a safer, more stable alternative to AC power.
• 27°C working temperature, quiet operation and protection for short-time immersion — suits aquarium setups where low noise and cooler operation matter.
• Fits 4 mm inner-diameter and 6 mm outer-diameter CO2 tubing — check both tubing measurements before connecting.
• Maximum CO2 system output pressure: 7 kg/cm² — confirms the pressure limit for compatibility.
• Mini inline form with flexible connection positioning — helps place the valve within the CO2 line.
• Includes a valve, power adapter, terminal cable and screwdriver — provides the listed components for setup.

A CO2 system needs a valve that can control flow while fitting into the aquarium tubing route. This compact inline model is made for aquarium CO2 systems, with its fit determined by the tubing dimensions and output-pressure limit. Its included adapter accepts universal 110–240V input, while the valve itself uses 12V direct current.

Will it fit my aquarium CO2 tubing and pressure setup?

Both ends fit CO2 tubing with a 4 mm inner diameter and 6 mm outer diameter, and the system output pressure must be no more than 7 kg/cm². These are the key compatibility checks for placing the valve in an existing CO2 line.

• Measure the tubing’s inner and outer diameters before fitting.
• Keep the CO2 system output within the stated pressure limit.

Where should I position the inline valve?

The inline design allows flexible placement in the CO2 connection, and positioning it closer to the diffuser supports more stable, responsive operation. The design is also presented as offering longer service life than other connection positions.

Use the valve with a check valve to help prevent water from entering. The unit is waterproof for short-time immersion; this is not a direction to leave it submerged.

• Place it near the diffuser when the tubing layout allows.
• Include a check valve in the setup to help prevent water entry.

What is included, and what maintenance does it need?

The package contains one solenoid valve, one power adapter, one terminal cable and one screwdriver. The adapter accepts 110–240V input to power the 12V DC valve.

Regular maintenance is needed. If the valve can no longer control CO2 flow, clean it before returning it to normal operation.

• Operating power: 12V DC at 0.8W.
• Working temperature: 27°C, with quiet operation.

This Clscea valve suits aquarium keepers adding an inline flow-control component to a CO2 system with matching tubing and pressure. Its mini format, included power components and flexible position make it a fit for an inline setup, provided the tubing and pressure stay within the stated limits.
