Electrical valve/Solenoid for RO/DI control

[InfernoST]

Hi Guys
I'm looking to semi automate my RO/DI unit and was looking for some sort of saltwater/reef safe solenoids or valves for the 1/4 inch hose, does anyone know where I can find them? I want one for my 20 gal breeder below the sump I use for ATO and 30 gal breeder above the sump for mixing salt. Any and all help is greatly appreciated.

Something like this for the RO?

Thanks Ming. Thats exactly what I was looking for.

Your top off water should be RO/DI, not salt water.

Most inexpensive fluid solenoid valves are not salt water compatible. I have been using these for my auto top off system since 2004 without any issues.

It is for RO/DI. I just want something to be able to withstand the saltwater environment since they are going to be right near the sump.
