Product Description

The Patent design of Valve cone is provides the secret to the Divator's ingenious system of pressure balancing.

As the demand valve functions, so the static pressure, provided at the hose supply will dimisish, as air starts to flow. Designs that rely on spring balancing and spring adjustments, to balance changes in incoming pressure CANNOT function dynamically and therefore provide either too much or too little pressure to match the change in demand effort.

The valve cone, working in conjunction with its associated balacing diaphragm actually use the incoming air to balance the opening effort (from hose pressure), so that whatever the pressure changes, the forces opening and closing the valve are fully balanced. The only mechanical effort needed for the breathing valve to function, is that required to overcome the small amount of friction at moving parts of the mechanism.

That is how the DIVATOR manages to repsond to the diver's changing breathing patterns in just 28 miliseconds; ten times faster than its closest competitor and how its test results reflect a lower breathing effort than any other demand valve in the World - even compared to servo valves (which designs are impracticable for use under water) !

For the DIVATOR, typical breathing rates induce WOB substantially less than 1 joule/litre/second; as here illustrated. This unprecedented performance depends on correct assembly and adjustment.
