I'm sure one ball valve is all you need...... but......I have two, cost another $14. I think it's kinda funny, because I use both, say I have one valve opened at 3/4 and my temp starts to drop, I open the second one maybe just a crack, the coals get a little bit of air from a different direction and the temp goes back up then I shut the second valve down. Temps stabilize again and I'm cookin. Just my .002
