WARNING
Use only standardised thread pressure
gauge. Do not use any type of adapter
between the 1st stage and the high pressure
hose connection.
The SORIUS 1000 regulator is designed with a
300 bars working pressure. When it is used
with pressures over 200 bars it is advisable to
use the optional threaded DIN connection to
the tank valve instead of the standard INT.
yoke connection.
SORIUS AND SORIUS ADJ REGULATORS
FIRST STAGE
This first stage combines very high performan-
ce with an extremely compact and functional
shape.
The SORIUS is a balanced diaphragm regula-
tor which gives you an intermediate pressure
which is always constant regardless of tank
pressure or depth.
The diaphragm completely separates the
"heart" of the regulator from the external envi-
ronment and provides high reliability over a
large number of dives.
It is manufactured from a single block brass
body which is copper, nickel and chrome coa-
ted. The internal component parts are in chro-
me/nickel coated brass, the springs in stainless
steel and the seals are made in nitril rubbers.
Four low pressure ports, with 3/8” thread, sup-
ply a constant intermediate pressure of 9.8
bars; the high pressure port has a 7/16” thread
and a flow reduction hole of 0.20 mm diam.
These high pressure ports are used to connect a
diving pressure gauge by means of a hose pro-
vided with a 7/16” male connection.
WARNING
Use only standardised thread pressure
gauge. Do not use any type of adapter
between the 1st stage and the high pressure
hose connection.
The SORIUS regulator is designed with a 300
bars working pressure. When it is used with
pressures over 200 bars it is advisable to use
the optional threaded DIN connection to the
tank valve instead of the standard INT. yoke
connection.
SORIUS and SORIUS 1000
REGULATORS - 2nd STAGE
The main body is made from synthetic resin
which is highly resistant to impacts, abrasions,
ultraviolet rays and chemical agents.
Incorporating silicone membranes and valve
seat with internal component parts in chrome
plated brass and stainless steel. The mouth-
piece is manufactured from medical grade sili-
cone rubber.
The second stage is a "downstream" type valve
with an air flow channel exploiting a "Venturi
effect". The result is an air flow delivery which
is perfectly controlled by the diver's breathing
action. Note: a normal breathing action produ-
ces a light air flow while a higher breathing
action, (due to heavy work or deep diving),
produces a high air flow which is supported by
the Venturi effect.
This system allows for low consumption of air
by reducing air waste as it is designed to per-
fectly fit the divers air demand.
The "downstream" valve also provides maxi-
mum safety as it is also able to work in case of
1st stage overpressure, by releasing the exces-
sive pressure, and allowing the diver to
breathe.
The low pressure hose is of the standard type
(length mm 760 - thread 3/8”).
OCTOPUS SORIUS
WARNING
Always check that the first stage to which
the SORIUS OCTO is connected is a SEAC
SUB product; if it is not so, verify that the
intermediate pressure set is comprised
between 9 and 10.5 bars.
Failure to respect this recommendation may
impair the 2nd stage performance and cause
serious accidents.
