ADVANTAGES AND EQUIPMENT
Two-stage safety pressure regulator S2SR (ÜDS)
The two-stage safety pressure regulator “S2SR” (Safety Two Stages Regulator) is a
combination of two series-connected pressure regulators.
The over-pressure safety device is designed to protect consumer equipment against
inadmissibly high pressures. If one of the two regulator stages fails, e.g. because of dirt and
other foreign bodies in the valve, respectively, the other regulator stage reduces the pressure
to 100 or 150mbar.
The pressure regulator is identified with “S2SR” on the type label.
When the pressure regulator is put into service, the display unit must be
GREEN
.
If the initial pressure rises over 80 mbar (models with 29 and 50mbar outlet pressure), the
display unit will change to
RED
. See TROUBLESHOOTING.
Optional thermal shut-out device „T“ (TAE):
At temperatures above 100°C, the thermal shut-off device is triggered and automatically
blocks the gas supply If the thermal shut-out device has been triggered, it must be replaced.
The pressure regulator classification F1-t acc. DIN 4811:2008 is also marked with "t".
