The first model of the Bialetti Brikka had closed lids of solid alumium, then they had a hole covered with glass, and now the hole is left open. This is intentional feature, for it seesm that early users gave feedback that the foam got better when the can was operated with opened lid.
Whether there were changes to the valve, I do not know, the most recent one looks like this, it is a ring that cannot be removed and that wraps around the chimney, while for cleaning the weight can be tied off. It contains soft rubber inside to seal the small opening hole in the chimney. This is what sets the Brikka apart from the earlier Bialetti cans, named Muka Express. These had no valve, no ring, no wight, and just two huge, very huge opening on both sides of the chimney's top.
P.S.
All three models can be compared here, would have saved me to take the pic:
