• Operating pressure: 0kg/cm² 10kg/cm² (0-142psi)
• State: normally closed
• Usage: water, air, diesel

it's not a burkert..

If you're willing to spend that amount of money on a solenoid, search the aquarium type. Keywords are 1/8 solenoid and you know the rest. Remember to make sure its' 110v for the north american standard.

There is even cheaper unit for 10 ish dollars. You're on the right track Jeff, there a other options beside a Burket. Though, I think there is someone who selling the Burket solenoid.

It's $13 w/ shipping.. My used Burkerts were $15 w/ shipping..and used to boot.
$5 solenoids don't 1) always list W and 2) aren't rated continuous duty..
Clippards are $10 plus $12 shipping plus "fittings" on fleabay.. (or $15 plus $4 plus fittings)

I must just be bad at bottom feeding..

 

[PlantedRich]

I might note that the bay is not a good place to buy fittings in many cases. When you really do a good search , they can be had for free with no shipping charged!

followup on solenoid: Well after testing it the best I can (and not being exactly sure if it the correct method) one thing I'm pretty sure of.. Is they have a very generous way of coming up w 2W...

After running it for an hour the coil temp was 126F.. and initial amp draw was like .76mA..
Simple "ohms law" calc puts it at 8W or better.. EEK..
Now I'm not exactly sure if this is a valid method of measuring "watt"s w/ solenoids but no matter how you look at it it is def. warmer than I was expecting.. Not too happy.. but live and learn..

I'll still put it in and give it a shot.. I'll see if it has any "lifespan" worth talking about.
My buzzy ASCO is sig. cooler though sig. more massive..

Coil seems standard so I might just check out a replacement coil and still look for other options..
Just an FYI............

 

[jeffkrol]

UPDATE biggest POS I've ever bought... SAD........ never could get it to seal and the body design is pss poor.. should have noticed...
yea yea yea.........

nonetheless, thanks for doing this, a local hardware store sells these exact solenoids locally, and I've always wondered ... btw, did the coil happen to get really warm when open? that would make me doubt it runs on 2w.

 

[AaronT]

Thanks for being a guinea pig for us anyhow.

I'm convinced the best bang for the buck are the SMC VDW21 series brass solenoids. They're really nice looking, high quality, 3 watts, and less than $30 new retail.

Well here is the kicker .. they are advertised as 2W.. When I checked the coil it was like 8ohms.. and when I did a amp draw on it was like 720mA.. @ 12V .. Yes it got warm..

I just got this somewhat cryptic response from the seller in this regards:

Seller's message:
"Dear friend, Sorry for any inconvenience! For the Wattage, the item need to be powered by 2A, after it being power, the current will change according to the liquid or gas environment of your system. And the Wattage change depends on current changing, so 2W is the instantaneous power.

anyone think that makes any sense??

I did find an honest dealer so to speak.. (that deceptive 2w-- blah blah number aside)
and he listed the "real" specs...
151143983116

Voltage: 12V DC / 24V DC / 220V AC (Please choose the correct voltage before you process the purchase)
Pipe size: 1/4"
Orifice: 2.5mm
Operating temperature: -5˚C ~ +80˚C
Wattage: 9.6W
Current: 0.8A
Operating pressure: 0kg/cm² - 10kg/cm²
State: normally closed
Usage: water, air, diesel

It is now on my (very) short list.. thanks..

Like this one.. Can't find 1/4NPT though...
SMC VDW21-5G-1-01N valve, compact, sgl, bras *lqa: Industrial Air Cylinder Accessories: Amazon.com: Industrial & Scientific

Oh, if you want 1/4" npt then you want the VDW31 series. Same solenoid, but 1/4" npt and a little bit bigger overall.

Freaking confusing numbering system....
OK
VDW31-6G-2-02 would be "ideal".. 1/4npt, 12V, 2mm orifice and .8MPa (116psi)

VDW31-6G-3-02 (3mm 54psi pres. diff) is useable as well...


VDW31-5G-3(or 2)-02 if I go 24V....

surprise surprise.. the "unusable one" is easily available... (29psi) this road looks familiar...

^ Jeff,

You need the pdf to determine the solenoid, there are a few suitable ones. Here is the model number of mine -

VDW20-15A-1

First guy ever to add active cooling to his rig. The solenoid gets pretty toasty too, maybe because it's stainless steel.

I used the pdf.. those were "translations" of their cluster...puppy (well it is not terrible, but I've seen better) The above specs are right from SMC..
And I know I'm being "picky" here.. as is my right....
Eventually I'll either need to "lower my expectations" or give up..
Right now I dribble so little CO2 that I could theoretically run solenoid less..
And if not for the AC buzz of the one I just removed.. and even considering it's "high " wattage..( a 1/2NPT solenoid dissipates a lot of heat, NOS "union made" ) it would have been fine.. BUT I'm not feeling the love to put it back in line.. yet...

Pretty sure in a short time I can get something to make do.. it just might cost me more than planned... or it might mean reconfiguring a bit..
I haven't even got to the check valve part yet (hint run multiple cheap ones in a pinch.. one will not do...)..

 

[jeffkrol]

VDW31-6G-2-02....................$45 (inc. shipping 4-6 weeks from Japan)
Best so far.. Solenoid is $30

 

[FlyingHellFish]

Go for It.

It looks good, I'm guessing 1/4 right?

There was a rumour that SMC discontinue the solenoid. Its sexy looking solenoid, probably why it gets so hot.

The price is pretty good for a stainless steel

 

[AaronT]

Look around some more. You should be able to find it.

Edit: Playing it safe is smart.

Wrong forum Aaron.
