For the Ex p control unit, purging gas valves are available in the "Proportional" or
"Digital" version. The difference between the two purging gas valve types is the
mode of operation:
Digital purging gas valve = on/off valve. Leakage air compensation takes place
via the setting of the manually adjustable leakage air needle.
Proportional valve = regulating valve. During the purging phase, the internal
pressure is regulated to 87.5% of p5 and during the operating phase to po.
