Well, knowing very little about valves, I didn't expect it to be so difficult. Since most reflex cameras achieve exposure times of 1 ms, I thought that there might be valves that can do the same. I now thought about a design which consists of a hammer and a poppet with a reset spring. All this...

>>Can you make a valve to look something like a gun (revolver) with the rotating chambers sized for the .3 cubic inches? You can recharge one chamber when discharging another. Well, I've got a number wrong, it should be 3 cubic inches instead of .3. But still, the idea with the rotating...

I think you are asking for information that I don't know. There is piping downstream of the valve, and there is a piston that blocks the pipe and moves when air is released from the tank. These things do not affect the choice of the valve. The only important things are those that I mentioned in...

I haven't adressed these two question yet: >>Can you use the pressure in the reservoir to activate the valve? Preferably not because the reservoir is not very large (approx. 150 cubic inches) and air should not be wasted in the process. >>Can you give the resevoir volume too? Because the...

The pressure increase in the tube after the valve is opened should be as instantaneous as possible. The reservoir is precharged. Apologies for not being precise enough. The 0.3 cubic inch needn't be accurate, it is an approximate volume. The air inside the reservoir is at room temperature...

What do you mean by slamming it open? This is certainly not very precise, let alone fast enough. A ball valve requires some force in order to be opened which cannot be supplied within such a short time as 50ms. After the 0.3 cubic inches of air are released, the valve should be closed...

Thank you for your help. It seems like I need to give a little more details. Air is stored in a reservoir at a pressure of 500 psi. When the valve is activated, the air should be released immediately. The capacity that must be released is about 0.3 cubic inches over not more than 50ms...

Hello everybody Does anyone know what kind of air valve fits the following requirements and where it can be obtained? -It should usually be closed -It should open within less than 10ms and stay open as long as it is activated -It should withstand air pressures up to 500psi -Its smallest inside...
