airline non-return valves

[foxy99]

Hi. Does anyone know anything about these and can explain it to me like I'm 6 years old....?

I've done a quick Google and am not seeing anything like the normal air-fitting I have (PCL, Vertex etc etc).

Bit of background may help....

I want to spray 2K (with air-fed mask) and do a little grit-blasting.

I have all the gear but never enough air.

So I thought I would be clever and buy lots of compressors and link them all up with Y-piece connectors.

Problem is the air from multiple ones doesn't all go to the place you want.

What happens is one compressor does all the work and any extra air you have goes to the emptiest tank instead of them all supplying the tool.

Absolute PitA but i was thinking there may be some sort of fitting compatible with normal airline fittings that will prevent any air going in the opposite direction of what you want it to go.



typical 'quick-connect' airline fittings. can you get ones with one-way valve?

It’s a check valve you’re looking for, I just googled airline check valve and quite a few popped up.

its probably not that one does all the work for that reason, it maybe that the pressure kick in valve is just a bit lower on one compressor?

I've done this and used one compressor for the mask and one for the spray gun by tieing two airlines together, its a bit cumbersome but it got the job done.

I like the look of them homersimpson

Nice and simple - with an arrow on them

Thanks

I've got a one way valve for water pipe inline in my air system for exactly the reason you stated, I run 2 compressors when blasting and found they wouldn't run properly in unison without it. As far as I know its rated to 10 bar, cost me around €20
