source of manually actuated 3 way valves (rated to 30 - 40 bar)

Hi,
First of all, I have to say that I find your site extremely useful... I really appreciate all the work you had to put in it

I know that my quesiton is unusual and I am perfectly aware of all the dangers of going past recomended pressure ratings of various parts (though I found that are built robustly enough to be safely used past their pressure rating... for example the one in the link below)

I use DCV valves for spudding... here is a thread showing how I used a 3 way valve to build a fully semi-automatic pneumatic rifle (using a QEV valve as the main valve)->

My question is, 'where can I find valves rated to 30 - 40 bar?'.

I found that indirect acting spool valves handle high pressures pretty well but I want to know where I can find valves that are actually rated to be used at higher pressures?? preferably ones that are manually actuated via a lever or button?

thx for spending time to read my letter

Thanks for the kind comment. They are few and far between.

Very interesting use of air valves, you have.

30-40 bar (450 to 600 PSI) really isn't that high a pressure, though you do not want to use a valve that is not rated for that pressure.

I simply used a search engine and typed in the string "high pressure valves" and found many sources.

Cheers,

Bill
