As of October 2019 all AP Oxygen Rebreather Valves are fitted with a needle-valve seat which offers progressive-opening of the valve.
When pressurising the oxygen system, for the first half turn or so it appears that nothing is happening. You should continue to open the valve a fraction at a time until the HP gauge needle just starts to move, if necessary, closing the valve slightly if the pressurisation rate is too fast, then stop and wait until it reaches full pressurisation.
NOTE: ALWAYS PRESSURISE HP OXYGEN SYSTEMS EXTREMELY SLOWLY - TAKING BETWEEN 1-2 MINUTES TO REACH FULL PRESSURE.
The new AP Oxygen Valves are an advance in safety designed to reduce the risk of sudden pressurisation and the generation of adiabatic heat which could ignite an oxygen fire in the first stage if contamination is present. They should be used in conjunction with the new AP Restricted Oxygen HP Hoses, also launched in October 2019.
The new needle-valve seat is made from a much harder material than previously and it is also high temperature resistant which makes it invulnerable to deformation in hot locations or if the diver routinely over-tightens the valve.
