I am not sure if you are trying to educate us on what valves are or if you are doing a sales pitch. I hope it is the first.

Well, I didn't know it was for degassing! So, thanks for that. I'm obviously a coffee neophyte when it comes to the information, but I've been drinking it forever, and liking it forever. Heck - I thought that was just so you could smell the coffee!
