DANGER
The tank valve must be replaced only by trained personnel; check that the connection
thread to the cylinder coincides exactly. Currently used threads are M25x2, as
set by EN 250 norm. However, there are still some tanks in operation which were
manufactured before the new CE regulations went into effect and contain a ¾ gas
thread connection. These two types of threads are absolutely
INCOMPATIBLE
and
their incidental pairing will cause explosions and/or
lethal accidents
. The most
serious risk occurs when a M25x2 valve is fitted onto a ¾ gas thread. A non-expert
may judge the connection to be screwed on sufficiently tight enough when accessing
visually but, actually, the threads will not be perfectly engaged and the valve will
be expelled from the tank during filling or at some other time, causing very serious
damages to people and property, potentially death.
!
WARNING
This valve can only be used on tanks that are compliant with EN 144-1.
SCUBAPRO valves (232 bar version) are the convertible INT/DIN type. You can use a 6-mm
Allen wrench to unscrew the adapter from the standard configuration, which is compatible
with regulators with INT connectors (w/yoke), in order to make it compatible for connection
to 232 bar DIN regulators (screw on).
The maximum operating pressure that the valve has been certified for is either 232 bar or
300 bar, depending on the version, used along with a first stage regulator with INT/DIN 232
or DIN 300 attachment respectively.
SCUBAPRO valves use 01 050 428 (white) polyurethane o-rings at the point of coupling with
the regulator first stage. These o-rings last at least four times as long as common EPDM 01
050 193 (black) o-rings.
SCUBAPRO valves come complete with a protection cap preventing scratches in the crucial
area where the seal with the regulator high pressure intake takes place. It is advisable to put
it in place every time the valve is not connected to the regulator first stage.
4. PREPARATION FOR USE
Before every filling operation verify that the valve connection is clear from dirt, undamaged
and that the o-ring does not show any signs of wear and tear.
If required, replace the o-ring using plastic or wooden tools to extract the old one. Do not use
metal tools that may harm the o-ring seat and degrade the seal, even with a new o-ring.
Before every filling operation, lightly purge the valve with air to remove traces of water, salt or
other debris that could enter inside the cylinder, causing damage or malfunction.
!
WARNING
Do not fill the cylinder with gases, oxygen enriched mixes (nitrox) or any gas mix
other than atmospheric air. Failure to follow this recommendation could lead to
explosions, fires or lethal accidents. Cylinder filling must be carried out using only
suitable systems supplying scuba-diving-grade air which is moisture-free, oil-free,
and contaminant-free.
