I know the OPD is designed to stop overfilling, but aren't these same tanks the ones you have to open "ever so slowly"? That feature is supposedly designed to stop a large spontaneous discharge if the valve (unconnected) opened up on a full "not empty" tank?
I kind of used the OPD as a generic label to describe these tanks.
I welcome your knowledge on the subject.
Read my previous post---above yours about OPDs and Excess Flow Devices.
Excess Flow Device is in the big green nut.......that is what trips (under several situations)
More about ACME NUT.....
