Also know as a non-return or anti back-flow valve.

Suitable for beer or aquariums. Most regulators do not have an anti-backflow valve built into them, so there is a chance that your beer/water can flow in reverse into the regulator causing irreparable damage. This is a cheap form of insurance that will save your regulator in the case that back-flow does occur. This check-valve is designed to be fitted in-line between the regulator and your equipment.

This valve will only let the gas flow in one direction, and if the flow was to reverse, it immediately shuts preventing backflow.

For aquariums running solenoids, a check-valve is a must, as once the solenoid shuts, the reduction in pressure in the lines actually sucks the water back into the regulator. You MUST have a check valve when using a solenoid.

Note: This check-valve is fitted with 6mm barbs, so people who use thick walled 4mm air line may have problems fitting it. 4mm standard airline can be persuaded on, but the best way is to get 5mm gas line (which we also sell), and then use a straight coupler to connect to your 4mm. 5mm line and 6mm will fit on the barbs without a problem.
