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.
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. "PRV" is marked on the type label of the pressure
regulator.
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.
Risk of asphyxiation from gas leaks in enclosed spaces.
High concentrations of gas can cause difficulty in breathing and lead to unconsciousness.
A discharge line
Insect protection with sieve
Insert in the breather on the 8 mm vent socket or screw into the female
thread G 1/8.
Check regularly that the sieve is not blocked. A blocked sieve can increase or
lower the outlet pressure and cause the safety overpressure shut-off valve (OPSO) to
respond. Clean or replace it as required.
