The proportional purging gas valve activated by the APEX control unit conducts the supplied purging gas into the Ex px control cabinet. During the purging phase the purging gas valve opens far enough to allow the max. purging gas pressure to be reached and accordingly ensures purging pressure in the encapsulated control cabinet. After the purging phase the purging gas valve closes. The leakage from the Ex px control cabinet is compensated by the linear opening of the valve. Only the actual loss by leakage is compensated when the purging gas valve is used.
