CO2 check valve advice

Please advise where I can find the best check valve. Prefer- brass or stainless steel if there is such a thing.

GLA offers quality equipment. But probably with a little digging around, you might find comparable items for less. However, if you find the prices reasonable (depending on your budget for such items), I find GLA to be one of the best sources.
