Description

Needle Valves are used for precision control of the flow of CO2 gas, which is not possible by use of the regulator alone. The bubbles should be fine tuned so that they are VERY SMALL and rise slowly and lazily to the top of tank, but almost become absorbed about 1-2 inches before reaching the surface. This way maximum use of the CO2 gas is achieved.

This needle valve is manufactured to high standards. The unit is a miniature precision needle valve, for sensitive and repeatable control of gases such as CO2. The Needle Valve can give precise control of CO2 gas when installed as directed, thus enabling the optimum use of CO2 gas in the aquarium.

Easy to use, your CO2 tubing simply pushes into either end of the Needle Valve. The small dial on the top simply increases or decreases the amount of flow you require when you turn it. This needle valve only accepts CO2 tubing of 4mm internal and 6mm (which is the same size tubing of all our CO2 tubing).

Tip: if you are planning on using one regulator to feed off to more than one diffuser, you will need one needle valve for each line of CO2. Failing to do this means gas will always find the route of least resistance and your flow rate will not be consistent. So to confirm, assuming you want 2 x diffusers in your tank, your set up would be:

1 x regulator, 1 x Y splitter, 2 x needle valves, 2 x non return valves, 2 x bubble counters  and 2 x diffusers.

A good needle valve with easy push in connection. A great way to split CO2 lines to another Aquascape without having to purchase extra CO2 regulator manifolds.

easy to use, it really allows a precise regulation of CO2 bubbles which my JBL pressure reducer ( u403 kit ) does not

this needle valve is for CO2 use only

I am looking to run 2 diffusers in the same tank from the one cylinder as I need to up the Co2 distribution in my 5ft tank, so im looking a 2-way needle valve or similar that will work for me

Ok. You will therefore need 2 x needle valves otherwise gas will simply go down the route of least resistance
