Anyone use Beaver dual-outlet valves?

[CRDiver]

Does anyone have experience using Beaver Sports dual outlet valves? It's a different style than the Beuchat Y-valve seen at some DIR websites, but retains the non-modular design, making it less prone to potential o-ring failure that exists with modular H-valve designs like those of OMS, Thermo, Dive Rite, etc. A picture of it is halfway down the Valve and Boots page on Beaver's homepage -

Probably a stupid question but...

Coming from the EU/UK does it have a burst disk?

It looks like a great design, btw.
