That's what I was saying originally- the LG300 regulator is built into the valve. I do not know what material it is made from, however, and it does appear based on it's layout and that diagram to be a fair bit larger than the 1250 valve assembly.
I'm confused by the term "air cylinder" you used earlier now- I had thought you meant the reservoir in that respect- but obviously we're talking about different things. |

I'm sorry for the confusion! I was using the term "air cylinder" for "air reservoir." I think the other part of the confusion is about the valve. I believe there is a regulator AND a valve in the LG300 and Dominator 1250 AND they are two seperate functional parts. I did not do a good job of explaining that. I also believe the regulator is built into the 1250's air reservoir because the connecting part is brass.
I found some more information about the Walther Dominator. The paragraph in this review under the heading, Based on a 10-meter target rifle, indicates that there is a regulator which probably brings the pressure down to around 2000psi. That seems more reasonable for the strength of brass. It also encouraged me to look further.
I found that the LG300 manual lists information for 21 and 28.5 foot pound versions (probably misconverted numbers since elsewhere they seem to be 16 & 21 joules - about 12 & 15 foot pounds?). It lists a different "system pressure" for each (both less than 1500psi). This seems to indicate there are different air reservoir versions like you suggested. I would guess the "system pressure" is the output pressure of the regulator.
Thank you for getting me to look at this in more detail!

Thanks for the links. That forum is run by 'rbva' around here. Must be his new thing- Roald's been holding back apparently!
Too bad the diagram's a bit blurry- but still usable if you blow it up enough.
Here it is:
