12v solenoid switch

[DEMPSEY]

Looking for help here. I have a 12v valve that is operated by first applying the current (2 wires) to open it and then you have to reverse the current to close it. Cannot seam to put a name on the switch that I need for to be able to do this.

Something like this?

That's it , why can't the dummy behind the counter not just say that . Explained what I wanted but could not put a name to it and he looks at me and says "is it in the catalogue.

There was a guy in Ireland selling DPDT toggle switches on ebay a while ago. I got a few and they are fine. As long as your current is not too high.
Brian, did you finally find a valve that will open under low pressure? The ones I have will only open under mains water presseue.
I'm looking for one to control outlet from a HLT.

I picked up a 5 x Danfoss HPA2 Solenoid Valves on Freecycle recently.
Are these of interest?

Here is the valve that is connected to Igor. Pulled it down from the attic to finish building it while waiting for my fridge to come home to me :

Hi John, I'm looking for valves that will open and close under gravity feed pressure. I got some a while ago, 12v normally closed, which work fine for controlling mains water pressure but simply stay shut on the outlet of a tank.
The job I have in mind is to keep the mash topped up from the HLT while sparging, controlled by a float switch.
If the ones you have will do that then I'm interested. A valve like that could do all sorts of other jobs too. Getting closer to automation!

Brian, I can't read the label in the photo. What exactly is that valve?

[johnrm]

Sorry, the yokes I have are solenoid only, no valves.
Not sure what you mean by staying shut, are your solenoids up to it?
I'm sure I said this before, but wouldn't a ballcock do the job?

Here is the valve that I bought. Power it and it stays open,reverse the current and it will shut and stay shut,reverse the power and it will open and stay open,reverse the power and..............well you get the idea. It is a full 1/2" bore and not like some of them that only have a diaphragm.

How's that valve working out? I watch with interest.
