Hi All,
I was wondering how is arranged/manufactured an electric swivel with screened paths. It is not clear to me if an electric penetration is different from a screen penetration or if they're exactly the same and they are simply located next to each other.

Does exist a check valve type which keep the piggability (gel pig) of the line where it is installed? (could it be useful a flapper valve type?)
Thanks,
Stefano
