RODI Question

[Kdocimo90]

Long story short, I want to add a solenoid valve to my top off as a safety feature. My question is, being that most normally open solenoid valves seem to be stainless steel, will that be fine to use? Only freshwater will be passing through it. My concern is that it will be "reef safe"

Check out BRS. It has valves specifically designed for that.

All I'm noticing are the Tunze ones? Is that what you're referring to?

 

[svogun]

The valve comes as part of a kit for auto shut off.

Look at the rodi accessories page.

Look at the rodi accessories page.

could you link it?
All I'm noticing are ASO valves and pressure switches for booster pumps..

I might be confusing what you are looking for. Unfortunately I'm at work and can't link the page to you. I'm responding via phone. The solenoid you are looking for is separate from an ASO?

Yes,

I'm looking for a Normally Open Solenoid Valve

Now I understand. Here is a link to what I think you need. McMaster-Carr The polycarb one likely will work/

They are normally closed unfortunately.

There is a nylon one that is normally open with adjustable flow control. Its 113 bucks.

Good luck and post some pics of you find what you need. Would be interested in this feature as well for mine.

I would go with the plastic version. That should work!

 

[Kdocimo90]

Any other opinions?

Only reason I ask is that the stainless steel comes wired and with all fittings and is also 1/2 the cost.

Lots to pick from at http://autotopoff.com/Solenoids/

I use these on multiple systems and no problem with heavy metals.

It's not coming into contact with any salt water, so I do not see what the issue is with using stainless.

 

[Kdocimo90]

okay, maybe I'll go the stainless steel route
