Aqua-Noa CO₂ Pressure Regulator Profi MV-BZ - Incl. Solenoid Valve

Aqua-Noa CO₂ Pressure Regulator Profi MV-BZ (with solenoid valve)

The Aqua-Noa CO₂ Pressure Regulator Profi MV-BZ is the most complete solution for professional CO₂ supply. This model combines the precision of the Profi series with the convenience of an integrated solenoid valve. This allows direct automation of the CO₂ supply, resulting in a safer and more efficient system.

Tip from our specialist: “The MV-BZ is our personal favorite. Because the solenoid valve is mounted directly onto the regulator, fewer fittings are required, reducing the risk of leaks. Connect it to a timer to automatically switch off CO₂ at night—this can save up to 50% CO₂ and prevents oxygen depletion for your fish.”

Why choose the Profi MV-BZ?

1. Integrated solenoid valve: No loose cables or additional installation work. With night shut-off, the CO₂ supply stops as soon as the lights turn off—exactly when plants no longer consume CO₂.
2. Dual pressure gauges: Complete control at a glance. One gauge shows cylinder pressure, the other displays the set working pressure.
3. Fully adjustable: The adjustable working pressure allows easy control of any diffuser or reactor, ideal for systems that require higher pressure.
4. Silent and energy-efficient: The high-quality solenoid valve operates virtually silently and consumes very little power.
