Here are the list prices for the Indexing valves shipped within the USA, if you wish a discount please order from your distributor. Where the valves ship to is how we decide who is the distributor please use the Map or if you don’t like Java, contact me and tell me where you want the valves shipped to and I can give you a link or contact information for your distributor.
The valves come in three different sizes. 1″, 1 1/4″, 1 1/2″
They also come in a few different bodies. 4 outlets, 6 outlets, 8 outlets (only in 1″ though)
There are cams that can be installed in the valves to allow them to operate different numbers of outlets.
For example the 4 outlet body can be cammed to run 2, 3 or 4 outlets and one would simply cap off the unused outlets if any.

Indexing valves do require a certain amount of pressure and flow to operate properly. Please contact me for assistance in pump sizing for your specific situation.
Aquaponics Indexing Valves, Sequencing Valves
Hello, I’m installing 3- 4x4x1 foot (16 cu. ft. each) media beds on my aquaponics system. Looking to maybe expand it to 6 beds at some point down the road.Want to flood and drain it and need an indexing valve and some advice. I will be using a 9-1200 gal danner submersible pump and 1″ pvc. What valve do you recommend? Any advice and a price on the valve would be greatly appreciated. Thanks,James
Above are the list prices but if you want to find the discount prices from your Aquaponics Indexing valve dealer in your area, Check out this link http://www.aquaponiclynx.com/indexing-valve-dealer-map.htm
and click on the map for your area till you get to the contact information for your dealer or to their price list.
Any of the six outlet valves can start out with a 3 zone cam and later be set up for 6 zones. Just make sure to cap the unused outlets in some non permanent fashion.
However, I’ve never tested the pump you mention with the indexing valves. I think it will probably be strong enough to operate the 1 1/4″ 6 way valve with the Gravity Modified Stem Disk Assembly as long as your heights are kept minimal. In my install where I am using a less powerful pump to operate the gravity modified 1 1/4″ valve, the fish tank is in ground and the valve is installed less than 18 inches above the water line and the tops of the grow beds are only about 18 inches above that. I made sure to upsize the plumbing from the pump to the indexing valve and I minimized the length of the plumbing runs.
The Danner MD18 (or 1800 gph) pump can handle any of the indexing valves with the low flow (normal aquaponics) stem disk assembly.
You will need a timer to turn your pump on and off since the valve only indexes forward when the flow to it stops.
Do you have anyone in Hawaii that sells these Valves?

Hi TCLynx,
I have enjoyed your website and prolific and informative posts on Aquaponic Gardening. I am in the process of building a deep water trough and raft AP system, but am having some second thoughts about media beds. My current plan is to continuously pump from the last trough into the fish tank which is maintained at constant height with a stand pipe. My question is can I use an indexing valve to alternately feed several banks of half barrel media beds using only the gravity flow from my tank? I will have about 3 feet of head (water level in fish tank to water level in grow troughs) to work with. I have never used an indexing valve but understand that I will have to interrupt the water flow for it to index. Does that mean I will need a solenoid valve to accomplish this task? Your thoughts on this will be much appreciated. I expect total system flow to be on the order of 20 gpm. Thanks for you consideration.
Bill
Hi Bill,
It is possible to operate an indexing valve under gravity flow provided you have a little bit of head to work with. However it is challenging to figure out some means of stopping/starting the flow to the valve since most inexpensive solenoid valves won’t operate under such low pressure nor will they allow enough flow through at those low pressure to operate the indexing valve.
I have operated (just for testing purposes) a 1 1/4″ gravity modified indexing valve using a Barrelponics sort of flush tank. The high water in the flush tank was about 26″ above the valve when the “flush” happened and it did work at least for the few hours I was testing it. Here is sort of a diagram
Anyway, not sure if this is quite what you have in mind to add an extra tank to manage the flow to the indexing valve and the media beds since you would need to make sure the flush tank was big enough to hold enough water to flood one bed at a time.
I am always working on other options and ideas for this. I have also made an automated high flow low pressure valve before but it quit working when a bug got fried in the electronics on me. Currently my big system is alternating between an extra pump in a Flush tank and when the pump turns off the FLOUT will sink to flood some other beds. See the Pumperflouternating blog post for more info on that.
Thanks TCL, I don’t know that I have enough head space to add another tank. Perhaps I can modify the Barrelponics flush system to operate on just the top 1 foot of my fish tank (~1,000 gal & 7 ft dia). That would give me a flush every 10 minutes or so and with a four port indexing valve would flood and drain each media bed every 40 minutes. I don’t know how the fish would respond to the water level rising and falling every 10 minutes, and it would add more “stuff” into my fish tank. How much head does a gravity modified indexing valve require?
I enjoyed reading about your adventures with the FLOUT system. Very ingenious adaptation.
I like to draw the flow from the bottom of my fish tank (hence the SLO drain in my fish tank and the FLOUT tank next to the fish tank.)
The indexing valve needs some where between 18-26 inches of head pressure with as full a flow as possible to really engage the gravity modified version.
Yes, I agree. I plan to use a stand pipe with on oversized sleeve that opens only at the bottom of the tank so water will flow up from the bottom of the tank to reach the top of the stand pipe.
Hey TCLynx,
The above Indexing Valve animation seems to imply that the indexing valve only cycles due to a start/stop of the water inflow.
IE It has no water coming in the animated piston pops up. Then water comes in and it cycles to port 1. Then when the water stops it pops the piston back up.
Does it require the water to cycle ON/OFF/ON/OFF….
And will a 500/1000 GPH pump be sufficient to work the low flow valve?
Exactly Blair, the valve does require the flow to stop and start in order to index forward.
And in general, NO a 500/1000 gph pump is not enough to operate the standard or low flow valves.
There is a gravity modified version of the valve that I have manged to run in a limited set up (not pumping very high) where I did manage to get it to work with a Quiet One 4000 pump which is nominally close to a 1000 gph pump but it has more lift than most other 1000 gph pumps I know of. I generally recommend a Danner MD 18 or similar pump to operate most of the indexing valves and I usually only recommend the gravity modified version of the 1 1/4″ valve when I discuss the set up with the person and determine that the lift will be small enough and that the Quiet One 4000 will be able to manage the job.
I usually use a repeat cycle timer to control the pump for these systems since it would require a more complex set up and a very big pump to use a solenoid valve to control flow to the Indexing valve.
Do you have any distributor in Hong Kong or Asia region?
