OPD Float stops liquid propane flow IN
Spring loaded shutoff valve prevents propane vapor flow OUT
Thank-goodness for it's safety design/features...even an idiot can fill them
Teenager filling those exchange cylinders has to have OPD open or they can't figure out why nothing goes in.....so they just leave the valves open.
The spring loaded shut off valve inside the OPD will not allow propane flow out if a ACME Nut is not attached.....center stub in ACME Nut pushes spring loaded valve open
