Intended use

The HEROSE combined pressure regulator is for the automatic regulation of pressure in stationary tanks
used for liquefied cryogenic technical gases. Without additional auxiliary energy, the combined pressure
regulator aims to maintain a predefined set operating pressure despite the operation of the tank and
temperature influences in the tank.
In addition to the pressure build-up and the pressure relief/overflow functions, the combined pressure
regulator has a safety function that protects the pipeline and its components on the inlet side.
4.3.1 Pressure build-up function
If the tank pressure falls below the set operating pressure, the combined pressure regulator opens in
order to restore the set operating pressure.
Flow direction AB
4.3.2 Pressure relief / overflow function
If the tank pressure exceeds the set operating pressure by 0.5 bar, the overflow function of the combined
pressure regulator trips in order to restore the set operating pressure.
Flow direction BC
