The automatic diluent valve functions on the same principle as a standard regulator. The membrane inside will depress when it is affected by negative pressure, opening a valve that adds diluent into the loop.
The integrated ADV rests inside of the BOV, making it much easier to find and manipulate with it.
The ADV does not have to be mounted to the BOV at all. It is a choice for divers who prefer to manage their loop volume by themselves, having maximal control in their hands.See all technicals
