simple question about valve types.

simple question about valve types.

simple question about valve types.

(OP)
I am looking for an idiot proof valve. Basically I would like to be able to press a button and have a valve open for a specific time. Say 1 second. No matter how long or short you press the button it still only stays open for 1 second.

I know I could do this with a solenoid valve and some simple circuitry but I would like to eliminate the need for electricity.

Any ideas would be greatly appreciated.

drive...

So you are looking for a device with a timer that does not use electricity...?

Something like those new automated valves that we find in bathrooms ?

How precise do you need the actuation time to be ?

It does not have to be very accurate. The valve will be used to fill a container with an inert gas. I just want to safeguard against someone leaving the valve open and wasting gas. I also want to make sure the valve is open long enough to fully pressurize the container.

RE: simple question about valve types.

Is a timed opening valve really the best way of doing this?  Sounds like what you're trying to do is to deliver a fixed volume of inert gas.

Surely a neater way to do this would be to have a small receiver connected via a changeover valve either to your gas supply or to your destination.

If your destination container is closed (you hint at pressurisation), then wouldn't a pressure regulator be all you need?
