This uses the same first stage as the Wind valve. The second balanced
servo-assisted stage consists of a front ingress membrane and
a back increased diameter membrane discharge valve "protected
by whiskers".
Exceptional performance during the technical tests (CE - EN 250)
places this valve among the elite.
The certificate states that the work and/or force needed for breathing,
"ext work of breathing", calculated using an impartial mechanical
test, is only 1.18 Joules/litre whilst the limit stipulated by
the CE EN250 standard is 3.0 J/lt. and that of the US Navy is
1.45 J/lt.
This data is even more exceptional considering it was recorded
under the most extreme conditions at a depth of 50 metres with
50 bar in the tank.
Main characteristics:
- 1st stage as Wind
- 2nd OW stage, body and cap in technical
polymer reinforced with fibre glass
- Balanced servo-assisted piston system
with mechanical opening.
- Rear discharge membrane, front ingress
membrane
- Valve Weight with hose is 750 grams
