Closed expansion pressure valve

[Ferlev]

Hi there.

Im looking fore a Closed expansion pressure valve, I have a small amount of water wich -might- boil, and I dont want it to escape. Where do i find such a valve? You can think of it like a baloon.

This looks like a great forum!

Are you looking for an expansion tank? These are used to prevent relief valves from lifting on hot water heating systems, etc.

Hmm, is this what it is called? Well, yes then, but I only have 19cm^3 water, so i really need a small one!
