Nice one, I'll send Camozzi tomorrow. Both are quite similar at around Cv 0.04.
Just so you know I'm sourcing metering valve with Cv 0.004 for very good price! I hope quality will be as good as price.
I'll keep you updated.
In regard to push in connector, I managed to source brass version without push-in (was really difficult, as prices from EU distributors are sky high!), the only problem is that these are twice more expensive than valve I sent you for tests. Now my question is who would be willing to pay around £10 more to have it in brass with build in standard tubing connector?
I'll get some and will se how these sells.
