Independent tests carried out by Notifying Board no. O426, in 1996 and 1997, have shown that the performance of the entire series of valves produced by us, (type OX and OW), meet the EN250 (CE) standards, as well as those of the US NAVY.

Main characteristics of 2nd STAGE in Carbon
- Pneumatic balanced servo-assisted piston (system patented).
- Venturi effect controlled by deflector with humidifying effect, Dive + PreDive command.
- Single larger size ingress/discharge membrane in special medical silicone
- Soft rubber cap (55 shore), hydrodynamic design
- Silicone mouthpiece
- Operating pressure from 8 to 15 bar
- Capacity from 900 to 4,000 litres/minute
Materials and specifications:
- Moving parts and valve body in Carbon.
- The high heat conductance of Carbon makes the valve functional in very cold waters (patented)
- The exceptional mechanical resistance characteristics of Carbon are as follows:
Enervation load in traction = 270 MN/m2 (45 is the value for good polymer
Enervation load in flexing = 400 MN/m2 (68 is the value for good polymer).
Elasticity module in flexing = 21000 MN/m2 (2150 is the value for good polymer).
- O-Rings in Viton for oxygen
- Stainless steel lever and membrane discharge support
- Special rich "OXYGEN" rubber hose with increased internal diameter, length 800 mm
- Weight without strap, 150 grams
- Intermediate pressure: 10.5 bar.
- Silicone membrane for pneumatic movements (patented)
