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.
Filter screen in the inlet connection of the pressure regulator
LPG may contain foreign matter, such as dirt particles. Over a certain size, these particles are
trapped in the filter screen in the inlet connection. If the LPG is not filtered, wear and tear of
the LPG system is increased up to complete failure. 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".
Optional excess flow valve EFV
Excess flow valve - EFV
Name for integrated hose rupture protection SBS according to EN 16129.
The excess flow valve (EFV) is an integrated safety device that blocks the gas flow if the flow
rate is > 110% than the target value of the pressure regulator. This can be caused, for
example, by hose or pipe rupture.
The gas flow is restored through manual intervention when the conditions that triggered the
safety device are no longer present. Restoration of the gas flow is facilitated by a manually
operated device. The pressure regulator is identified with "EFV" on the nameplate.
The excess flow valves (EFVs) are put into operation by pressing the operating button until
the pressure has equalised.
Optional pressure gauge
The product is equipped with a pressure gauge to indicate the inlet pressure. The pressure
gauge can be used for leak testing (see "Model with pressure gauge" at LEAK TESTING).
