22" Trunnion Monunted Ball Valve as a Single Valve DBB

[Rovshan]

Hi all

Could you please check and advise which type of seat is indicated?
DPE or SPE
and can we use such type of seat valve as a DBB/DIB as a single valve?

Looks like SPE to me.

So no. Can't be used as a single valve DIB

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

This Valve will be on Pig Receiver side.
1. The Option is to provide two 22" Ball Valve with a bleed between
2. Review and confirm if one valve can function as DBB.

All I have in hand is Valve GA and to provide the correct answer I need to know the type of seat.
