Default What to look in solenoid?

Im thinking of buying solenoid and dont know what to look and how to diverse good from bad?

Im looking on ebay on this list

http://tierwelt.shop.ebay.de/Fische-...&_sop=15&_sc=1

Germany has same standards as Croatia so im sure it will fit and also have some frends there which will bring it to me.
Is low consuption , aka 1W or 2W, good mesure of quality?

And how do i connect solenoid directly to regulator? I have 1/4 inch female connector on regulator and solenoids have 1/8 inline connectors

The Bürkert 6011 solenoids are in made in Germany. They are very high quality items rated at 4 watts. There are two new models with Buna-N seals, one is brass and the other is stainless steel. Buna-N is designed for use with CO2. It is the same seal material that is found in paintball guns.

Buna-N Model numbers and specs: https://www.aquaticplantcentral.com/f...tml#post545465


The standard model Bürkert 6011 solenoids use Viton seals. This is a very good all around seal material.

Do note that Bürkert has many models of the 6011 solenoids. These 4 models mentioned above have specs that work well for our use, but there may other models that will work too.


Bürkert has several styles of 2056 DIN cable plugs. The solenoid comes stock with a standard cable plug with no added features. You can also get cable plugs with LED's. These LED models came come with the LED only and no added circuitry. Also, you can get LED cable plugs with varistors and with varistors and rectifiers.

LED cable plug info: https://www.aquaticplantcentral.com/f...tml#post547111


You should be able to order from your local Bürkert distributor in Croatia.

There are a few ways to do this. You didn't mention anything about an elbow, so I will omit it.

One way is that you can use a 1/4" male NPT x 1/8" male NPT reducing hex nipple.



Another way is to use two parts. You can use a 1/4" male NPT x 1/8" female NPT reducing hex bushing along with a 1/8" NPT hex nipple.

Thanks LeftC, i think youre most knowlegable man on net about regulators and valves in hobby. I have tried to contact Burkert representatives in Croatia about month-two ago, following your posts on barr forum, but without luck. First i sent them email, then called but without much interest from their side, and im really not a man to force my money (or anything) to somebody. So , im continuing the search. Ive looked on german ebay for solenoids or "magnetventil" how they call it and prices start from 20 euros up. Do you think some of these would be good?

Most of them have a 1-2.5 W rating, do you think thats possible, seems so low?
Oh and i found interesting Aqua Medic solenoid with some pulse technology which enables it to consume energy only during closing/opening of the valve . Interesting, but somewhat expensive, about 80$ and out of my league. I didnt know such solenoid exist...

EDIT Eh and for regulator , i was thinking of having everything (Swagelok, safety valve and bubble counter) in line but everything fixed to little board which will be fixed to regulator with the screws). It would be neat and i wouldnt have to chase for adapters (and S class Swagelok is inline anyway)
