BOV Shrimp

 The Bail-Out Valve

BOV Shrimp is a CC/OC Bail-out Valve with a 2nd stage regulator incorporated into the 
mouthpiece with the ability of supplying the diver with open circuit breathing gas when 
needed.

The CC/OC valve allows to easily and fast switch between the close circuit (the CC mode) 
and the open circuit (OC mode) by one hand. It is operated by rotating the knob on the 
front of the BOV.

When the BOV is switched to the CC mode – the breathing loop is open via the mouthpiece 
and allows the diver to breathe on the rebreather closed circuit. 
When the BOV is switched to the OC mode – the breathing loop is closed and allows the

diver to breathe on open circuit via the 2nd 
stage regulator. In this position no water can 
enter the breathing loop even when the BOV is 
out of the diver’s mouth and submerged.

The 2nd stage regulator has an adjusting knob 
allowing to adjust optimal breathing resistance.

One-way directional valves (mushroom valves) 
provide and ensure the correct breathing gas 
circulation in the breathing loop in the correct 
direction from the inhalation counterlung to the 
exhalation counterlung. If needed, the flow 
direction can be changed by reversing the mushroom 
valves in the BOV.

Breathing hoses are connected to the BOV via the unique and secure Click-Lock Bayonet 
Cuplers. There is impossible to connect the breathing hoses incorrectly due to different 
keying on each bayonet connector on the loop.

BOV Shrimp is compatible with most known CCR units, just use the right set of Couplers. 
There are available couplers for Hammerhead, JJ-CCR, MEG, KISS, Optima, Isnpiration/ 
Evolution, rEvo, SF2, Titan and another customs made Couplers.

SM BOV Neo

The side-mount Bail-Ot Valve

SM BOV Neo is a Bail-out Valve with a 2nd stage 
regulator incorporated into the mouthpiece with 
the ability of supplying the diver with open 
circuit breathing gas when needed.

SM BOV Neo is primarily intended for FLEX2 CCR 
side-mount unit.

The CC/OC valve allows easily and fast to switch 
between the close circuit (the CC mode) and the 
open circuit (OC mode) by one hand. It is 
operated by rotating the knob on the front of the SM BOV.

When the SM BOV is switched to the CC mode – 
the breathing loop is open via the mouthpiece 
and allows the diver to breathe on the rebreather 
closed circuit.

When the SM BOV is switched to the OC mode – 
the breathing loop is closed and allows the diver 
to breathe on open circuit via the 2nd stage 
regulator. In this position no water can enter the 
breathing loop even when the BOV is out of the 
diver’s mouth and submerged.

One-way directional valves (mushroom valves) provide and ensure the correct breathing gas 
circulation in the breathing loop in the correct direction from left to right, from the inhalation 
counterlung to the exhalation counterlung.

The SM BOV 2nd stage regulator is supplied with diluent via the LP hose running parallel to the 
breathing hoses and connected to the Diluent MAV via the Shut-Off Valve.

Breathing hoses are connected to the SM BOV via the

unique and secure Click-Lock Bayonet Connectors. It is

impossible to connect the breathing hoses incorrectly

due to different keying on each bayonet connector

on the loop.

DSV Shrimp

The Diver Surface Valve

The DSV Shrimp is a Diver Supply Valve allowing to open and close the mouthpiece of the 
breathing loop. It is operated by rotating the knob on the front of the SM DSV by one hand.

When the SM DSV is switched to the OPEN mode – the breathing loop is open via the mouthpiece 
and allows the diver to breathe on the rebreather closed circuit.

When the SM DSV is switched to the CLOSE mode – the breathing loop is closed and in this position 
no water can enter the breathing loop even when the BOV is out of the diver’s mouth and submerged.

One-way directional valves (mushroom valves) provide and ensure the correct breathing gas 
circulation in the breathing loop in the correct direction from the inhalation counterlung to the 
exhalation counterlung. If needed, the flow direction can be changed by reversing the mushroom 
valves in the BOV.

Breathing hoses are connected to the SM 
DSV via the unique and secure Click-Lock 
Bayonet Connectors with one L-90° Coupler.

It is impossible to connect the breathing 
hoses incorrectly due to different keying on 
each bayonet connector on the loop.

DSV Shrimp is compatible with most 
known CCR units, just use the right set of 
Couplers.
There are couplers for Hammerhead, JJ-CCR, 
MEG, KISS, Optima, Isnpiration/ 
Evolution, rEvo, SF2, Titan and more.

SM DSV

the Side-mount Diver Surface Valve

The SM DSV is a Diver Supply Valve allowing to 
open and close the mouthpiece of the 
breathing loop. It is operated by rotating the 
knob on the front of the SM DSV by one hand.

When the SM DSV is switched to the OPEN 
mode – the breathing loop is open via the 
mouthpiece and allows the diver to breathe 
on the rebreather closed circuit.

When the SM DSV is switched to the CLOSE

mode – the breathing loop is closed and in

this position no water can enter the

breathing loop even when the BOV is

out of the diver’s mouth and submerged.

One-way directional valves

(mushroom valves) provide and

ensure the correct breathing

gas circulation in the breathing

loop in the correct direction from

left to right, from the inhalation

counterlung to the exhalation

counterlung.

Breathing hoses are connected to the SM DSV

via the unique and secure Click-Lock Bayonet

Connectors with one L-90° Coupler.

It is impossible to connect the breathing hoses incorrectly

due to different keying on each bayonet connector on the loop.

SM DSV is compatible with side-mount CCR units FLEX1, FLEX2, T-REB, SF2 as well as 
another units if there are used customs made Couplers.
