ADVANTAGES AND EQUIPMENT
Safety gas pressure regulation device
Caramatic DriveTwo for the operation of LPG-
operated gas equipment in caravans and motor
caravans while driving, consisting of: automatic
changeover valve, integrated low pressure regulator
with pressure relief valve PRV, mechanical crash
sensor with control knob, operating and reserve
display, sealing nut, non-return gas valve,
test device, screw aid and wall bracket.
• By default, the version with outlet connector RVS 10 is fitted with an adapter to
connect 8 mm piping.
• Test device for the leak testing of LPG systems without removing the product.
Installing a gas filter
We recommend installing two gas filters onto both safety gas pressure regulation device inlet
connectors. (2x Caramatic ConnectClean order no. 71 781 01). LPG may contain foreign
matter, such as dirt particles. From a certain size, these particles are trapped in the filter. If no
gas filter is installed, wear and tear of sensitive components is increased and the complete
LPG system may break down.
FUNCTION DESCRIPTION
Pressure relief valve PRV
The pressure relief valve (PRV) is an automatic safety device with limited flow that is installed
in the pressure regulator to protect connected devices against inadmissible high pressures. If
there is inadmissible high pressure at the outlet side, for example due to high temperatures,
the PRV opens and relieves the excess pressure through the breather. When the pressure
falls, the PRV closes again automatically.
A connection to the open air must be created if a pressure regulator with PRV is to be
operated indoors, inside housing or in any other areas that could be at risk.
"PRV" is marked on the type label of the pressure regulator.
Automatic changeover valve are used in two cylinder systems
• Automatic changeover to the reserve gas cylinder as soon as the gas cylinder on the
operating side is empty.
• The gas cylinder can be replaced without interrupting operation.
• Only alternating withdrawal is possible.
• Display of which side the gas is supplied from.
• The non-return valve installed in the inlet nozzle prevents unintentional gas leakage when
changing the cylinder.
• Even gas supply through the optimum use of the gas cylinder content.
• Europe-wide use through the use of country-specific high-pressure hose assemblies
with excess flow device (2x Caramatic ConnectDrive - not included in the delivery).
