GLA Atomic Check Valve – Nature Aquarium Check Valve
High-Pressure CO2 Protection in a Compact, Precision-Machined Form
Engineered for serious aquascapers and high-performance planted aquarium CO2 systems, the GLA Atomic Check Valve is a premium check valve designed 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 typical plastic check valves.
With a cracking pressure of 25–30 PSI, this valve is specifically designed for higher-pressure CO2 systems—ensuring reliable one-way flow while helping protect regulators and solenoids from back-siphoning.
Key Features:
- Cracking pressure: 25–30 PSI – Ideal for high-pressure CO2 setups
- Heavy-duty anodized aluminum – Corrosion-resistant and built for long-term durability
- Push-connect fittings – Quick and secure connection for compatible CO2 tubing
- Directional flow control – Clear arrow indicator for proper installation
- Sleek matte finish – Clean appearance for modern planted aquarium systems
Why Choose the Atomic Check Valve?
Designed for high-pressure planted aquarium CO2 systems, the GLA Atomic Check Valve delivers reliable one-way flow and long-term equipment protection in a compact, precision-machined design.
Installation Note: Always install with the arrow pointing in the direction of gas flow (from regulator to diffuser). Compatible with standard CO2 tubing (verify tubing compatibility before purchase).
Listing is for one (1) check valve. Please adjust quantity if multiple check valves are needed.
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.
