Divesoft BOVs, DSVs and ADVs

Where peak performance in the work of breathing is essential.

Explore our range of in-house made Dive Surface Valves (DSVs), Bailout Valves (BOVs) and Automatic Diluent Valves (ADVs) which are manufactured from the highest quality materials and fully configurable based on your preference, compatible with most of the units on the market.

Dive Surface Valve (DSV)

The dive surface valve is a compact and reliable mouthpiece that is optimal for divers who do not need the extra functionality of the BOV and prefer minimum bulk with the streamline design. The mouthpiece maintains the classic open and closed positions.

All DSVs are fitted with original Draeger mushroom valves.

Bailout Valve (BOV)

Our bailout valve combines an open-circuit and closed-circuit mouthpiece in one elegant body. You can toggle between the two positions quickly and effectively without ever taking the mouthpiece from your mouth. The BOV offers unparallel modularity and represents the safest strategy for an immediate switch to open circuit in the event of an emergency on closed circuit.
All BOVs are fitted with original Draeger mushroom valves and 2nd stage APEKS regulators.

Manual Addition Valves (MAVs)

Two manual additon valves located at the mouthpiece, one for oxygen and one for diluent to replace the need for standard add valves that run over the shoulder to a gas block. The design of the valve’s conserves space, and are intuitive to operate.

Automatic Diluent Valve (ADV)

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.

DSV / BOV OPTIONS

DSV

The Dive Surface Valve offers a reliable and mechanically extremely simple solution for rebreathers with 2 operating positions: opened (Dive mode), closed (Surface mode). It is ideal for divers who seek a simplistic design and extreme durability.

Unique Manual Addition Valves

"Find your mouth - Find your MAVs"

The Manual Addition Valves are part of every CCR Liberty configuration. The Oxygen addition is located on the exhale side to avoid breathing in too much PPO2 at depth. On all FMCL configurations, the MAVs are located on the counterlungs. On all BM BMCL and SM configurations, the MAVs are conveniently designed to be next to your mouth. There they can be easily found without having to look for them. As the diver in trim would have his/her arms in front of their body they can always easily locate the MAVs for manual addition of gas should it be needed. The position of the MAVs is particularly beneficial in tight restrictions where the diver is always able to reach them. The MAVs can also be used as a mean to Off-board gas.

Single Hose Adapter - SHA

Any BOV can be equipped with SHA which reduces the number of hoses feeding the 2nd stage regulator of the BOV and the MAV from 2 to 1 LP hose.

ADVs

Our in-house built ADVs will provide you with precise delivery of Diluent. Just select your favourite type based on its features.

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 ADV integrated into BOV rests inside of the BOV, making it much easier to find and manipulate.

The ADV can also be integrated into the T-piece of the inhale counterlung which is the most popular option. It is a choice for divers who prefer to manage their loop volume by themselves, having maximal control in their hands.
