Digital Purging Gas Valve for Ex pz Operating Equipment

Marking

 II 3G Ex nA IIC T4

Ambient temperature

-10 °C to +55 °C

Description

The proportional purging gas valve activated by the SILAS controller conducts the supplied purging gas into the Ex pz control cabinet.

During the purging phase the purging gas valve opens far enough to allow the max. purging gas pressure to be reached and ensure purging pressure in the encapsulated control cabinet.

After the purging phase the purging gas valve closes. The leakage from the Ex pz control cabinet is compensated by the valve’s linear opening.
