The valve is
designed to convert
cylinder pressure into
breathable air pressure
at constant flow rate.
Valve flow around 20-26
liter per minute and
outlet pressure 4.5-5.5
bar for input cylinder
pressure 20 to 200 bar.
Intricate design and
precision machining of
small parts ensure
smooth valve movement
and leak proof joints at
