Aquarium CO2 Timed Electric Valve | Digital Timer & Bubble Counter

Automate Your Aquarium CO2 System with Precision Timing

Take the guesswork out of planted tank management with this Aquarium CO2 Timed Electric Valve. Designed for freshwater planted aquariums, this motor-driven solenoid-style valve automatically opens and closes your CO2 supply on a programmable schedule — keeping your aquatic plants thriving without constant manual adjustment.

Whether you're running a single-tank setup or managing multiple aquariums, this valve delivers reliable, hands-free CO2 regulation. The built-in digital display timer lets you set precise on/off cycles, so your plants receive consistent carbon dioxide during daylight hours and your CO2 supply is safely shut off at night.

Key Features

• Motor-Driven Valve Control: The valve is driven by a motor mechanism — not a continuous electromagnetic coil — meaning the motor only works for approximately 5 seconds during each open/close cycle. This eliminates continuous heat build-up and significantly extends the product's service life.
• Digital Display Timer Switch: Easily program your CO2 schedule using the intuitive digital timer. Set specific on/off times to match your lighting cycle for optimal plant growth. Refer to the included manual for simple, step-by-step setup instructions.
• Durable Metal Valve Body: Constructed from metal for maximum durability. The valve body is waterproof and built to withstand the pressures of a CO2 system safely.
• Available in Single or Double Head: Choose a single-head unit for one tank, or the double-head version to serve two separate aquariums from one controller.
• Wide Voltage Compatibility: Works with AC 100–240V input, compatible with both 110V and 220V power systems globally.
• Generous Cable Length: Includes a 3.5-meter total cable length for flexible placement near your aquarium setup.

Frequently Asked Questions

Q: How does the CO2 timed electric valve work in an aquarium setup?

A: The aquarium CO2 timed electric valve connects between your CO2 cylinder/regulator and your diffuser. Using the built-in digital timer, you program specific on and off times. When the timer triggers, the motor-driven valve opens or closes in approximately 5 seconds, automatically controlling CO2 flow to your tank without requiring manual intervention.

Q: Why is a motor-driven valve better than a standard solenoid valve for aquariums?

A: Traditional solenoid valves use a continuous electromagnetic coil that stays energized (and warm) the entire time the valve is open, which can shorten the valve's lifespan over time. This motor-driven valve only activates its motor for about 5 seconds per switching cycle — open or close — eliminating constant heat generation and significantly extending the unit's overall durability.

Q: Is this CO2 electric valve compatible with my power outlet?

A: Yes. This valve supports AC 100–240V input and is available with both 110V and 220V plug options, making it compatible with most standard household outlets worldwide.

Q: Can I use this valve with multiple aquariums?

A: Yes! The double-head version of this valve allows you to control CO2 flow to two separate tanks simultaneously from a single timer unit — ideal for aquarists managing multiple planted aquariums.

Q: What is the maximum CO2 pressure this valve can handle?

A: The valve is rated for a maximum operating pressure of ≤1 MPA (approximately 145 PSI), which is well within the range of typical aquarium CO2 regulator output pressures.
