RE: Globe valve jammed & not operating
You mention nothing about the type of actuator, the service history of the valve(new or old, well or poorly maintained, operated often or infrequently etc).
Is it jammed open or closed?
What flow rates does it handle?
What are the materials of construction?
Is Dowtherm oil vapor the process fluid?

Do share such reasons for jam & i want to know more about Dowtherm oil vapour will be helpful please
RE: Globe valve jammed & not operating
Did anyone check these before the system was commissioned? (obviously not)
It could be anything from corrosion shipping to damage in installation.

How many "Hand wheel operated 1" CL.800 Globe valves, Body materiel A105 Trim 8" that were installed failed?
When was commissioning? How long ago?
Good luck,
