ball valve passing
(OP)
We performed passing test on MOV's on low pressure, we found valves passing, I would like to know if the high pressure above 60barg will seal the seat leakage.
thanks in advance

RE: ball valve passing
What type valve? Are you thinking that higher seat loading might seal the valve?
Perhaps a new API 6D ball valve with resilient seat is bubble tight at the factory. Once the testing group runs the nasty, rusty hydrostatic fluid that they call water the seat is often scratched and passes.

Svi -- post a new question.
As an aside, I admit to getting a chuckle out of this thread's title, because of the euphemistic useage of "passing" to describe someone who has died. So I read "ball valve passing" as meaning "my ball valve died."
