OPERATING PRINCIPLES

The pressure regulator reduces the unregulated pressure from the liquid gas container in a single stage to 1-4 bar.
In the event of an impermissibly high increase in the outlet pressure at the pressure regulator, the response pressure of the overpressure safety shut-off valve (OPSO) is reached, which then closes automatically and shuts off the gas flow upstream of the pressure regulator. The respective operating status of the OPSO can be seen on the visual display.

Clear = open
Red = closed

If there is a further increase in pressure, e.g. due to the OPSO not closing completely, the pressure relief valve (PRV) automatically releases a limited amount of the gas flow into the atmosphere after the set response pressure has been reached.
