Izzo 安全閥

The 2.2 bar rating was exactly what I needed to get the pressure right on my espresso machine, and the 3/8" thread fit perfectly with no adapters. It's been a week of daily shots and the valve hasn't leaked a drop.

Replaced the old valve on my Gaggia and the 2.2 bar rating seems spot-on for proper steam pressure. The brass threads felt solid during installation, no leaks so far. Only gave four stars because I wish the packaging included a new o-ring.

The 3/8" connection matched up perfectly with my existing lines, and the 2.2 bar rating does its job without fuss. Only wish the package included a spare gasket, but the valve itself feels solid and leak-free so far.
