CO2 Regulator

Post by Twitch on April 30th 2011, 17:15

1. Is it possible to repair a CO2 regulator? (I'm guessing not)

2. Is there anyone willing to donate a working CO2 pressure regulator to the group?

1. Maybe, what is it doing, or not doing?

2. Are you looking for a specific size?

The dial is not functioning, and it is hissing, you can also feel a gas leak.

So, by dial, I'm assuming you mean inside the gauge? It's hissing, and you can feel the leak. Where on it can you feel the leak? If its on the supply side, and the gauge is malfunctioning, it might only be a bad seal from supply to the body, and could be as simple as an O-ring. Although, if the leak is from the body itself, and the gauge is on the fritz, it could be a breach in the stem area that supplies the gauge. Have you tried the soapy water test yet to find out where the leak is? That might be an alright place to start.

Yes, gauge, not dial. You're right. The needle in the gauge basically moves freely, and will sway from side to side as you tilt it.

The leak appears to be from the body. I have not put it in water.

I'm thinking it may not be worth trying to repair. I think it was less than $20 new.

I'm hoping someone has one they are willing to part with.

I might be able to find one, I'll look through my odds and ends bins.

What kind of PSI are we talking here? I may have one that will work.

That's what we are trying to figure out is the sweet spot. I can tell you the tests I have run so far at 80 to 100 PSI take about 1/2 to 3/4 gallon in volume of air to do what we want. I'm thinking if we move to higher pressure say 250-ish we can have a lower volume.

There is a commercially built model that runs 250 psi... So we may have success there. Right now it's a process of finding the right pressure to volume ratio. Unfortunately the air compressor I have is dinky and only goes up to about 100 psi, and I don't want to build a pressure vessel of that size if I can avoid it.

Well, now I'm scratching my head scratch what I have can't handle that high PSI. If I get a chance to take a look at it, I may have a better idea for a few things that may work.

Also, have you thought about using individual 12gr for each "charge" on the vest? I mean, it would be a pain to get the trigger timing sync'd but it could solve the volume issue, but like I said, I feel like I'm talking out of my butt here because I haven't seen the mechanism you are working on.

Yeah the 12 gram idea has been kicked around, and I don't think we're going to go with that as the desire is to have a remote trigger which is going to require more hosing, so we will likely need more volume than that, although they run at about 850 PSI, their volume is very low. Also I don't want to over stress the other components in the process of delivering that gas.

A remote trigger you say. Is this for your mine or that vest? If it's the mine then I have been thinking in the wrong direction, on the vest 12 grams could work because of the way it could be set up with individual smaller devices set off together, if it's a mine, or claymore kind of device, then I have to think more about the remote trigger rather then the modular upkeep a vest with multiple small devices presents. I'll do a bit of brainstorming to see what I come up with.
