Latched open check valve
Latched open check valve
(OP)
I am looking for a check valve that can be latched open to allow reverse flow when desired. This will be in LNG service, -250F, 24" Class 150. Any thoughts?

RE: Latched open check valve
This sounds like cryogenic service, right? Lots of real thick insulation?
If it is possible I recommend a Bypass line with a Car sealed closed (Locked closed) line spec block valve. It could be smaller than the existing 24" line size.
prognosis: Lead or Lag

All for the sake of two tees, two elbows, two flanges and an isolation valve??
Normally if you're installing a check valve there's a good reason for it. To be capable of removing that safeguard, there has to be a very good reason or the check valve isn't needed in the first place...
