What is the difference between a plain lifting lever and a packed lifting lever in a safety valve handle?

The difference lies in whether the moving part of the lift wrench is sealed or not. PACKED: Sealed, used for valves with closed valve covers. PLAIN is unsealed and used for valves with open valve covers.

Plain can also be used for valves with closed valve covers, while packed must be used for those with open valve covers. Is that plain lever sealed?
