TECHNICAL MANUAL
REGULATOR
This DC280/380 is a component designed to be used in an installation of pure
gas. The final manufacturer is responsible for preparing appropriate and adequate
instructions and warnings for the final user.
200 bar (2900 psig) for models DC280
300 bar (4350 psig) for models DC380
Outlet pressure adjustable between
0,2 to 1,5 bar (3 to 22 psi)
0,4 to 4 bar (5,8 to 58 psi)
1 to 10 bar (14,5 to 145 psi)
1 to 16 bar (14,5 to 232 psi)
3 to 35 bar (44 to 508 psi)
Flow for which i (coefficient of irregularity according to ISO2503) ≤ 20% and R
(pressure rise coefficient according to ISO2503) ≤ 20%.
From –40°C to +60°C (from –40°F to 140°F)
Between –40°C to +70°C (between –40°F to 158°F)

This unit has a non-collectable safety valve which only protects
the regulator and never the system downstream of the latter
For models DCL280&380 =1 bronze filter, gas filtration threshold of
98% of the particles stop of 45µm.
For models DCI280&380 =1 stainless steel 316L filter, gas filtration
threshold of 98% of the particles stop of 48µm.
This filter only protects the regulator and never the system
downstream.
