ADVANTAGES AND EQUIPMENT
Two-stage safety pressure regulator S2SR
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 80mbar (models with 29 and 50mbar outlet pressure), the
display unit will change to
RED
. See TROUBLESHOOTING.
