dear all,

"Cerified firesafe by Llyods to DOT Rule 54 App. D for use in fire water mains offshore and marine installations".

Who can tell me more about the DOT Rule 54 app. D. What does it contain or require?

In those mentionned installations, what is the most common seat design? PTFE with metal back ring?

Thanks in forward!!

Regards,
MT
