Lip-seal for body seal (Trunnion 3 piecies ball valve)
I have been facing problems with 10in 2500# trunnion ball valve with unacceptable external process fluid leakage. The reason was the lip-seal that seals between body parts. In fact there is no visual indication of gap extrusion and it looks like it collapse in the opposite pressure direction...- Andresmrj
