BOV – (Bail Out Vaulve)

BOV
The breathing mixture is delivered to the Bail out vaulve (BOV) through the corrugated hose from the left. When inhaling, the mixture passes through the inhalation valve to the mouthpiece and then into the diver’s respiratory tract. When exhaling, it passes through the exhalation valve into the corrugated hose on the right.

Inhalation valve
The inhalation valve ensures that the exhaled mixture cannotdirectly return to the inhalation bag and is not repeatedly inhaled by the diver without the removal of carbon dioxide and the addition of oxygen.

Exhalation valve
The exhalation valve directs the exhaled mixture via the corrugated hose to the exhalation bag. It ensures that the diver does not directly re-inhale the exhaled mixture. The exhalation valve is situated within the connection of the right corrugated hose.
