Excess flow devices ....
To reset just close the cylinder valve/wait 30 seconds and SLOWLY open
**No need to disconnect AMCME Nut, NO need to open anything down stream
Device trips due to increased floe....leave system pressurized and it will reset when you reopen the valve
Propane valves........SLOWLY Open FULLY or Close FULLY
The valves have seats that seal in FULLY open/Closed positions
During transition from Closed to Open to Closed the valve stem is seal via a packing gland. Valves are intended to be FULLY Opened/Closed
Packing gland is subjected to Full Propane pressure (100# - 250# +)
Do NOT rely on them .....
