MicroFlex Valve – CO₂ solenoid valve

The Aquario MicroFlex is a compact solenoid valve for aquarists who dose CO2 into a planted tank and want to control the gas line electronically. It closes the CO2 flow to the aquarium, so it suits setups where a pH controller switches the gas supply automatically.

Why it matters

• Compact body: the small design fits behind or beside the tank and is easy to conceal in the cabinet.
• Operates at 12 V: the low operating voltage is the basis for the manufacturer's claim of stable work without overheating.
• Ready to connect: brass-free fittings for 6 mm hose are included, along with a power supply and cable, so no extra parts are needed for the gas line.
• Status LED: a diode indicates that the valve is working, which makes it easy to check operation at a glance.

What it works with

The valve is designed for CO2 systems in planted freshwater aquariums and is compatible with the Aquario AquaViva PRO pH controller, which supplies the required 12 V directly, so the valve can be connected to it without the included power supply. The data does not specify tank volume, so check the gas capacity of your cylinder and regulator against your setup before installation.
