Default Valve testing a 4212

I have recently acquired a very large valve - a 4212H, I believe.
Is it possible to test one of these huge valves ?
It is undoubtedly beyond me !
I have ascertained the filament has continuity and thats me done!
Is this a service that is provided by anyone ?
Many thanks
