You have an ASME TANK (not a cylinder)
Tank does not require the propane cylinder OPD service Valve only propane DOT cylinders do.
Your TANK has a internal float. Part of the 'FILL Valve'....liquid propane goes in
Your Service Valve allows Vapor to come out
Valves on cylinders function as fill and service valves hence the reason for the OPD (Overfill Protection Device)
Float on fill valve (to its right is 'liquid' level fixed tube that goes to bleeder valve. Both at set at 80% liquid level
