I hear that Penco makes a low pressure index valve for Aquaponics. Does anyone know where I can find one or locate a low pressure index valve for my system?

I'm not sure if that's the correct company name but TCLynx here on the BYAP forum has them on her web page and has had setups that used them so she can tell you more than most people here. Here's the site - http://www.aquaponiclynx.com/aquaponics-indexing-valves-list-prices

Talk to me about low pressure indexing valves.
Please keep in mind that they are not no pressure.
They still require a certain amount of flow and pressure to operate and they are a passive design as in they need the flow of water to stop and start in order for them to index to the next zone.
I have worked with the manufacturer to come up with modification to allow even lower pressure than the valves they sell for irrigation and stuff but the smallest pump I have used with them was around 1000 gallons per hour.

If you tell me the pump (make/model) and the height at which you intend to pump, I can probably tell you if the valve will work for you and if so, which stem disk assembly you will need to get.
