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.
Risk of asphyxiation from gas leaks in enclosed spaces.
High concentrations of gas can cause difficulty in breathing and lead to unconsciousness.
