The digital purge gas valve controlled by the APEX or SILAS control unit directs the supplied purging gas into the Ex p control cabinet. During the purge phase, the purge gas valve opens and thus ensures a purging pressure in the encapsulated control cabinet. After the purge phase, the purge gas valve closes. Any leakage losses occurring in the Ex p control cabinet are compensated for by an integrated adjustable leakage air needle valve.
