GLA Atomic V2 – Nature Aquarium Check Valve
High-Pressure CO₂ Protection in a Compact, Precision-Machined Form
Engineered for serious aquascapers and CO₂ enthusiasts, the GLA Atomic V2 is a next-generation check valve built to handle the demands of pressurized CO₂ injection. Crafted from anodized aluminum with tight machining tolerances, it delivers superior durability and long-term reliability compared to plastic alternatives.
With a cracking pressure of 25–30 PSI, this valve is purpose-built for high-efficiency CO₂ systems—ensuring one-way flow while guarding against dangerous back-siphoning that could damage your regulator or solenoid.
Key Features:
- Cracking pressure: 25–30 PSI – Ideal for high-pressure CO₂ setups
- Heavy-duty anodized aluminum – Resists corrosion and wear over time
- Push-connect fittings – Quick and secure connection for CO₂ tubing
- Directional flow control – Clear arrow indicator for proper installation
- Sleek matte finish – Blends cleanly into nature aquarium setups
Why Choose the Atomic V2?
This isn’t your average check valve. The GLA Atomic V2 offers professional-grade performance and peace of mind for your planted tank. Whether you're running a single diffuser or a multi-tank manifold system, the Atomic V2 ensures reliable gas flow and equipment protection—day in, day out.
Installation Note: Always install with the arrow pointing in the direction of gas flow (from regulator to diffuser). Compatible with standard CO₂ tubing (check fitting size before purchase).
Customer Reviews

This is the best check valve, likely nothing better available for the price.
I use several check valves in my fish room and always without fail these things stop working. Granted I use the phony barbed ones that claim to be stainless but they are not. The spring inside gets rusty and sticks closed or wide open. I usually get about 4-6 months out of them. This valve, it’s never going to rust and has the perfect spring tension from a stainless steel spring. Couldn’t be more pleased with its function.

GLA makes the best co2 gear.
This check valve is absolutely exceptional. Really like how tight it closes compared to my UNS valve. The speed fit tubing connections seal the deal for me. CNC alloy can’t be beat.

High quality check valve.
Originally came to buy another black super check valve GLA offers but saw this one and it’s super nice. Full alloy construction, but does operate at higher psi only, but not crazy. I’d say it’s normal for today’s atomizers. Definitely heavy duty.
