Solenoid Valve??

Clippard and Burkert
Parker

 

If heat is an issue, the solenoid that comes with Azoo regulator has virtually no heat problem. I live in tropics, with tropical temperature. I nearly can' t feet it when I touch it.
Not sure about other factors though.

 

Clippards are 6 watts
Burkert are 4 watts

 

Hello Nipat,

I also have an AZOO regulator, and we live in the same country, but my solenoid valve gets pretty hot. I am just wondering if it has a problem? Have you ever opened one up, I was just wondering if I should open it up and have a look, I have noticed my solenoid valve seems to be very hot today. If this one gives up the ghost I will go to "the market" and get a Parker from Sea Sun. One more question, have you adjusted your output pressure on your AZOO?? Just wondering, I bumped mine up to about 2 bar today to see if I could get a more stable bubble rate. It worked to a point, but I have the standard needle valve on it at the moment and they are rubbish, I have a Nupro on order from Rex Griggs, but it may be a month before it gets here.

Cheers,

My solenoid has turned off 2 hours ago.
I'll check it tomorrow if it's hotter than before.

You can open it very easily. I think you probably
already know how to open it but I'd say it away.
Just unscrews those 4 screws and you are done.
I opened it once when my bubble counter was still
bubbling after shutting it off, and solved it.



I have problem about stability of bubble rate only
for the first few days after changing to a new cylinder.
After that it's very stable, the tolerance has been around
0.5-1 bubble per minute. My working pressure had been
around 25PSI. The stock needle valve is hard to adjust though,
too coarse.

Azoo's manual says the factory setting is 4-6 KG/CM2.
But I've found that it is just the pressure when we attach the
regulator to a cylinder for the first time, then open the cylinder's
valve when the solenoid is closed. It will gradually turn down
to real working pressure shortly after use (probably 30 mins).

A few days ago, I've changed the working pressure to 21-22PSI.
The reason is nothing special. It's just because I was trying
connecting something inbetween the regulator and the solenoid,
and tried to find a suitable working pressure. The ‘experiment’ failed.
And I just leave it at that (21-22PSI). Still works fine.

BTW, the stock solenoid uses 1/8" NPT thread.

Cheers

 

Ok, Thanks Nipat. I'll open it tomorrow and see if I can see anything amiss, ya, you have the same one as I, but the needle valve got knackered by the shop that I took my tank to for refilling awhile back, although the needle valve isn't any good anyway, as you said, too coarse. Now I have a spare tank, and just swap them out myself, before I just took the tank with regulator to the shop and let them change it over and they closed the needle valve with a pliers, I could see the marks on it when I got it back. That's the main reason I can't seem to keep a steady rate I would suspect. My mistake for not keeping the Reg, with me and trusting these guys thinking that they know what they are doing. Oh well, live and learn. My Nupro should be here soon, I hope. Thanks again Nipat.

Azoo regulator is something ‘high-end’ here. So that darn shop might has never seen one and
don't know how to use it. But they still should've known how to use a needle valve

Cheers

PS: Don't forget to close the cylinder valve before opening the solenoid.

 

Hi

May I ask were you got it? I know that AP.com carries them.

Thanks,
