O2 cleaning a Drager valve

4ster · 8th November 2007, 02:50

I am in the process of cleaning a Drager valve and 4 liter cylinder. I've re-read the "Oxygen Hackers Companion" and thumbed through my text from my blending course so feel pretty comfortable with the basics.

I am looking for an exploded diagram of a Drager valve. I have a pdf copy of the Dolphin service manual but the valve in the manual is probably an older Atlantis style, anyway it is a different valve than the ones I am used to.

One of the things I am trying to figure out is if I should remove the burst disk as part of cleaning. Drager's burst discs are...well... unique. If I know the geometry of the valve I might be able to decide if the burst disc needs to be removed.

Can anyone point me to a drawing of the valve? If you have cleaned a valve feel free to walk me through the process.

Here your answer :

the older style piston regulator is very easy to disassemble EXCEPT one point : to extract the piston, you need to pass a screw or something else that won't scratch by the MP holes to push it outside.
