Valves, the difference opening time makes.

Post questions and info about pneumatic (compressed gas) powered cannons here. This includes discussion about valves, pipe types, compressors, alternate gas setups, and anything else relevant.

An interesting comparison.
I may still have my very first spudgun in a box in the attic. It might be quite funny to do a comparison video against HEAL which uses about 4 times the pressure, and has a valve over a hundred times faster.

and she is in fact in a barrel of an older cannon unfortunately she is gone now

Any connection between those two facts? No, I'm kidding.

I've run out of pets now, both the family guinea pigs have passed on - they were very interesting creatures, but they didn't have much ability to climb walls - still, they would half clamber up the chicken wire that made up most of the sides of their hutch if they heard or smelt something interesting - and then they would make an absolute racket until someone gave them some food.

Oh, I forgot I used to have those.

The copper chamber bursted becauses of the 4X rated pressure.

But the vids still keep the old thing alive, 2 inches of steel at 500m dident stand a chance.

WTF is that supposed to mean? I take it that you have no work that you are proud of. Zen, i have seen alot of your comments are "interesting", you are by no means better than anyone here-same goes for me and the rest of the members.
Cursed be the day that it becomes against forum rules to mention ones cannon.

Rant over.

Are you serious you had a 4000 psi gun
Can somebody link me to these vids please.
4000psi is an amazing amount of pressure how did you get your chamber that high and I bet it had amazing destructive potencial :twisted: but 4000psi is also a little bit suicidal

ok, does a qev have the same action/caracteristics as a sprinkler valve but can handle higher pressures?
