DPE ( Double Piston Effect) Seats in Trunnion Ball Valves
(OP)
Are DPE seats best in gas application than in liquids? Where does it make sense to use besides the fact that is serves as a secondary barrier in case one seat is compromised?
Thank you,

That's all I know.

2nd q It doesn't as dpe seats lock in presure between the seats which needs a separate relief, though mainly for liquid systems where thermal expansion needs to be taken into account
