Overview
This 12 V solenoid valve is a direct-fit spare part for CO₂ regulators with G5/8 or W21.8 gas-thread inlets—commonly used on aquarium, hydroponic, and planted tank CO₂ systems. It’s modular, removable, low-heat, and corrosion-resistant, making it both effective and safe.
Key Features
- Thread compatibility: Available in G5/8 and W21.8 (also CGA320) to match industry-standard CO₂ cylinders .
- Low-temperature operation: Designed to run at body-safe temperatures—won’t burn on touch .
- Corrosion-resistant: Constructed from stainless steel and aluminum alloy—durable for wet CO₂ environments .
- Silent & efficient: Consumes ≤1 W, with near-silent actuation ideal for home use .
- Modular design: Easily removed or added to dual/side-gauge regulators or integrated bubble counters without tools .

Why It Matters
- Regulator maintenance: Replace only the solenoid valve without changing the whole regulator.
- System reliability: Ensures CO₂ dosing systems remain leak-free and responsive.
- Energy-efficient: Keeps standby draw minimal—ideal for day/night CO₂ control.
- Quiet & safe: Maintains silent operation and won’t overheat—even in enclosed setups.
Compatibility & Use
- Confirm your CO₂ regulator uses G5/8 or W21.8 inlet threads.
- Disconnect tubing and power before replacement.
- Screw the solenoid into place & reconnect electrical supply (12 V DC).
- Test for leaks and operate both manually and via controller/timer.
