I disagree. Exxon should not allow for a 3% total of older valves like that to be left in service. Is that not the reason 97% were upgraded? For safety?

The valve itself was not unsafe. The action to remove the gear shaft assembly was. The design of the valve and assembly was old but in normal operation it works safely. As others have said when the valve wouldn't operate properly, they should have stopped and got others involved. At that point the line should have been isolated, cleared, and tagged out to safely do the work.

Not likely for safety. The valve wasn't unsafe.
They were likely upgraded to new valves because they no longer make the model when they needed new valves
