The bellman will set onboard gas supply to a slightly lower pressure than surface supply pressure to the bell gas panel, so that it will automatically cut in if surface supply is lost. After locking out of the bell the diver will close the diverter valve and open the return valve on the helmet, to start the gas reclaim process.
An oxygen safety relief valve DN250-safety valves. A safety valve is a valve that acts as a fail-safe.An example of safety valve is a pressure relief valve (PRV), which automatically releases a substance from a boiler, pressure vessel, or other system, when the pressure or temperature exceeds preset limits.
As a person breathes, the body consumes oxygen and produces carbon dioxide. Base metabolism requires about 0.25 L/min of oxygen from a breathing rate of about 6 L/min, and a fit person working hard may ventilate at a rate of 95 L/min but will only metabolise about 4 L/min of oxygen [10] The oxygen metabolised is generally about 4% to 5% of the inspired volume at normal atmospheric pressure, or ...

The term “modular” applied to the setup of tooling and casting stations in the Windsor and Romeo engine manufacturing plants, not the engine its
The most powerful versions they built were in the Atlantique 300 at 207 kilowatts (281 PS; 278 bhp) from a turbocharged, 12-valve 3.0 L iteration, and they successfully raced at the 24 Hours of Le Mans with the 600LM with a twin turbocharged, 24-valve 3.0-litre, pushing out over 450 kilowatts (610 hp) in race spec, and the road-going spin-off ...
Ribbon diagram of human carbonic anhydrase II. Active site zinc ion visible at center. From . At least five distinct CA families are recognized: α, β, γ, δ and ζ. These families have no significant amino acid sequence similarity and in most cases are thought to be an example of convergent evolution. The α-CAs are found in humans.

On 15 May 2009, the damaged radiator panel's ammonia tubing was mechanically shut off from the rest of the cooling system by the computer-controlled closure of a valve. The same valve was then used to vent the ammonia from the damaged panel, eliminating the possibility of an ammonia leak. [ 287 ]
