Burkert OK, Me not so OK

Hi Left C,

The Burkert works fine, it was the connection between the tubbing and the diffuser that gave me all the headaches. I am guilty of rushing to conclusion:(

Oh, yes, I made sure the solenoids were installed correctly. Just like Matt's and yours instructions and research.

Glad to hear your solenoid isn't the problem. Truthfully, I've never heard of a burkert failing for defect...they are pretty sure to check them before they send them out.

Sorry .... I've been away. ... Boötes Void ... ! (flu)

I'm glad that it is working fine.

The only problem that I know about with the Bürkert solenoid is that silicone tape can get trapped in it causing it to not close completely. This isn't the Bürkert's fault, though. It might happen to any solenoid that we would use with silicone tape. I has happened to me with my original "The Best" regulator that AquariumPlants.com no longer carries.

The electro magnet part of my Burkert failed yesterday; it was buzzing, then it stopped as did the CO2 flow. I have mine all of the time; I have a sump with plants that is lit when the top is off at night. I unscrewed the post and removed the actuator and spring that lets gas flow when the magnet is engaged. Is there a problem for doing this? Is there another fitting that I can get and remove the solenoid; the bubble counter seems to be integrated.

How do you know the unit has failed? What model number is your unit?
I have witnessed the exact same buzzing noise on a brand new unit. The unit I had with the buzzing noise runs silent now. In fact I'm using it on my vts253a-1993.
post a picture of your configuration to see if we can help.
ALso how long have you ahad the unit and where did you get it? Who installed it for you?

open the tank valve with the solenoid off.
open the needle valve all the way (or remove it-dsiconnect from co2 tubing).
plug in the solenoid.
unplug the solenoid to stop gas flow.

try again if the noise doesn't go away.

the noise could also be related to backpressure and weird components (too high a cracking pressure, etc.).

It looks like the orientation of the black box/plug piece (on a burkert) does not matter as far as function. I can orient in the most convenient way to keep the cord out of the way? In various pictures, it looks like folks have them facing a variety of ways. i.e. the white sticker side of the black box/plug piece could face the "npt" side, the "P-->A" side, or the input or output sides?

generally speaking, you can attach it in any 90* orientation (if that makes sense).

This is what mine looks like but has no "P" or "A" printed on it. Just curious if this one is oriented correctly ?? Thanks for the help !

The arrow is the direction of the flow of gas.


I had spoke to Burkert folks myself and they had recommended to mount if straight instead of sideways for best performance.

So in the pic I showed is it correct or should it be changed? I don't quite understand the whole straight vs. sideways...straight in relation to what ?

The way I'm the picture is the right/prefered way to mount it for optimal performance.


Sideways means how it's mounted in the pic in the link. That works but sometimes causes issues.
