CGA347 Valve?

[Chief Ten-Beers]

Has anyone disassembled one of these? If so, is there a way to make it so you don't have to push in on it to open and Close? I have noticed that when I want to shut it off in a Hurry that if it's not just right, it locks up until you get it in the right groove to turn? lol Or would it rquire replacing it with a different Valve?

Remove knob, then remove spring.. Replace knob..

Good to know! Do I need to empty the Tank first? Or just make sure that I don't turn the valve by removing the Spring?

If you are talking about the valves on scba tanks such as scott firemen tanks, then you can just screw in the nut and it will do the same thing. You dont have to remove the spring. Thats what i do.

Thanks so much Guys! They both work like a Champ! Tightened them and "Presto"!

Going to do this as well. I find that characteristic of these valves horribly annoying

I replaced mine with the Joe B. Valve with dual gauges, it was pricey but worth it in the long run. It has a really nice glycerin filled gauge so there’s no doubt about the fill pressure in your guns.

I agree that it may be annoying for us airgunners, but they are crucial for their intended purpose.

It's definitely a trade off between ease of opening/closing/adjusting the valve and the safety of knowing the valve won't get opened/closed/adjusted by accident. It's nice to know that the behavior of the knob can be easily changed to suit the user's preference. I'm glad I saw this thread. Thanks guys.

Hey tenbeers, no need to take off the jam nut, just tighten it until it stops, done. Makes all the difference in the world when the bottle is over 4000 and the guns max is 3000. Good (read easy) control of the valve and it's easy to not overcharge the gun, Just go slow. I love love love filling from an air bottle, quick, easy and convenient. Minimizes running El Cheapo to once a week, think I will just buy another 30 min. bottle, ganging the two at home gives me 9 liters, can set it up to take one with for use in the field. Changing out the CGA347 valves will be the simplest way to do that. Would only need a high pressure ball valve between the two bottles. The big one hour SCBA bottles are hard to find and pricey.
