Hi all ... my first post is actually a question. I have been searching for the name of a specific type of valve. More specifically the name of the valve in a refillable butane lighter (the intake valve). The little brass valve that is usually at the bottom. I need something similar for a proeject I am working on but after looking for a while I have yet even to come up with a specific name for it. Also, if somebody could tell me where I could find some (doesn't have to be brass - as long as it is metal) ... I need about 20 minimum to begin with. Thank you very much, Iza Bl..
