3.3 PRV
The gas pressure regulator is fitted with an automatic safety device
(PRV)
1)
� If the gas pressure regulator is not working properly, for
example due to dirt or other foreign mateiral, the safety valve opens
and releases the overpressure� The connected consumers are thus
protected from an impermissibly high pressure� The PRV closes auto-
matically after the pressure is reduced�

PRV = Pressure Relief Valve

tic switchover between the gas cylinders� As soon as the operating
cylinder is empty (<0,5bar), the switchover system switches to the
reserve cylinder� Switchover is indicated by means of red or green
windows (Fig� 3-1)� Both windows relate to the operating cylinder�
