Proportional ball valve

[Ismaclst]

Roberto, if I recall you were looking for a proportional ball valve at one time? I found one on eBay at 186 dollars. Here is the item number for that listing, 222044516416. Would this work with the RA? I know the listing shows it with a stainless steel body but I contacted the seller and they could sell one with a pvc body instead.

Yes, I do believe it would.
The item description says you can order 0-10VDC signal.
Make sure to choose that.
Then any analog output from RA would be able to control the valve.
Just for future reference, I'm going to include the name of the valve in case the ebay page is no longer available in the future.

Interesting. I think I saw someone looking for this too. What would you plan to do with it?

I thought about using it in conjunction with my DC return pump to keep the overflow level at a specific height. I decided to go with a simple off/on valve and teeing that off the main drain.

The purpose of that valve would be to open if the other drain became too restricted and caused the overflow to rise too high.

So here is the bypass valve I added to my drain. The purpose of it is to open if the main gets too clogged, since it already is restricted. I want it to turn on when my overflow is 87 or greater. I want this to stay on until I manually turn it off. This will be using port 2 and water level 2. Would it be as simple as this?

Code: Select all

 if (ReefAngel.WaterLevel.GetLevel(2)>87) //Overflow
      ReefAngel.Relay.On(Port2);

I think it would work as long as you don't use port2 for anything else.
Another alternative is to override it on.

Code: Select all

if (ReefAngel.WaterLevel.GetLevel(2)>87) //Overflow
      ReefAngel.Relay.Override(Port2,1);

Thanks, Roberto!
