Pawfly3-Way Aquarium Air Flow Control Lever Valve Manifold for Air Pumps Fish Tank Multi-Port Distributor Splitter with 3 Non-Return Check Valves and 4 Suction Cup Clips

We run air lines to different tanks and these work great.

I have an air pump that is too strong, so I used this to split the feed into 2 stones. Worked great! And you can adjust the flow independently. The suction cups also work nicely to keep the hose (and hence, the stone) in place!

10/9/2023: have been testing for a while, and I LOVE this product! I didn't wanna buy another air pump when I came across these types of valves, and WOW! It works for both my tanks and it's not even loud (excluding air pump). It fits both my tubings and has some pretty strong power! That being said, you do have to adjust it to each sponge filter, one works perfectly fine but when you try to adjust it, the other filter stops. Otherwise, it's a great product! Anyone who has multiple betta tanks or ones with low-flow, I definitely recommend! Will be buying again if I get more tanks!

The models of this type of device that are made entirely of plastic fail quickly - control levers break off or the hose attachment points just fatigue and break from nothing more than the weight of the tubing.Enter these beauties from Pawfly - solid metal, tough as nails. And the manufacturer stands behind their products 100% - can't ask for much more. There is no reason to worry that you may get one of those rare items that slipped through QA or that may have been damaged in transit to you - the manufacturer will take care of it promptly.The adjustments are easy to make, you don't need to use all the ports - just close off any not yet in use. This means you can get one with more ports than you need so that you will be sure to have an extra port or two when you do.My only complaint (and this is not really a complaint because I had no intention of using them) are the suction cups. They really smell badly of chemicals and I tested one out just to see how they were - they don't stay stuck to the glass very long. Again, I wasn't buying this for the suction cups, so this is not an issue for me, and frankly, should not be an issue for anyone since what we are buying here is the control valve ;-)Bottom line - I highly recommend this product and will shop from this store again (and already have!).

I have 3 Air Stones and 1 Air difuser Bar, the airflow to each one is verya easy to set.

Inexpensive, didn't last long. After a couple of weeks, it started leaking. Replaced it with a more reliable brand, which has worked fine ever since.Very limited dynamic range. The difference between full-off and full-on was only a slight twist. Couldn't adjust it very easily.

These valves are perfect for splitting air into different directions. Especially like the ability to adjust how much air is flowing to each valve and ability to shut any of them off entirely. These are very solid and work perfectly. The check valves in addition were a pleasant addition.

I bought this to replace a worn out plastic gangvalve unit for my 26 gallon aquarium.The set does not come with instructions, but by referring back to the Amazon product Q&A, I figured it out.The anti-siphon lock is very important! The worn out plastic gangvalve did not have one and I ended up with a damaging leak after a power outage. The anti-siphon accessory with this unit should resolve that problem.The metal gangvalve itself is awesome. So smooth and precise, not awkward and klunky like the plastic unit was.Assembled it all with my existing pump in about 30 minutes, and it is delivering just the right amount of air exactly where I want it.Thanks!

For some reason I assumed that 4-way valve was going to be made of plastic but it is actually metal. I was impressed by the use of quality materials on this product. The 4-way valve works excellently and is super convenient and handy for controlling my air pump output, I really love it. The suction cups are a bit weak and don't seem to want to stay stuck to the glass long term, but I am using them as extra security for keeping my air lines concealed under gravel. Since the gravel gives a lot of weight to hold it down anyway, I'm not too concerned about the suction cups. If I want good ones, I will just order a pack elsewhere. The the back-flow valve doesn't 100% guarantee protection of water back-flow (it works if it's angled just right but if its not, some water drips past.) I recommend that if you're going to rely on the back-flow valve in this set, test it out first (when its NOT connected to your air pump!) to make sure you have it set up in a way that it will actually work.I really only bought this set of tools because of the 4-way control valve and since that's the item that is perfect, I'm rating it a full 5 stars.

I'm very happy with this product, I think it works well. I like the fact that it's metal and easy to control the amount of air that goes in my betta bowls. The suction cups work well if you put them on by working from one side to the other instead of just pushing them on from the middle of the cup. They keep my lines in place, which means I don't have to hold the air stones down by other means. I would buy these again if I ever need more and can recommend them highly.

all the vales work and don't seem to have any issues i had it or only 1 month so don't take my word on it

They work great, and easy to use.

excellent value for money
