Yes Infernal you are right. The pressure put on the actuation valve in a piston/diaphram valve is the same as the pressure in the chamber.
But it is for a brief period of time, just the split second it takes to vent the small area holding the diaphram.
Whoever appeals to the law against his fellow man is either a fool or a coward.
Whoever cannot take care of themself without that law is both.
For a wounded man shall say to his assailant,
'If I live, I will kill you. If I die, You are forgiven.'
Such is the rule of honor.

the venting isn't where it would break if it only held 90psi the holding wile the two halfs of the valve equalized pressure is where it would mostlikely break.SquishY wrote:But it is for a brief period of time, just the split second it takes to vent the small area holding the diaphram.

The blow gun is taking pressure as long as teh chaber is filled.

200 psi - crazy?
I don't know what it is with your US blowguns, but in the UK, we can easily get 10 bar (145 psi) blowguns, which could probably be used up to 300 psi without any trouble.
I suppose it's just differing economies, but a lot of what you say makes little sense. (For example, over here, QEV's are about the same cost as sprinkler valves)
But, then again, you can get your pressure rated PVC much easier.
*Shakes off off-topic mode*
Normally, most components have a minimum 2:1 safety ratio. Which means you can probably take your components up to about 50% over what it suggests without death or injury.
Just be careful if you do.
