16" Butterfly Valve @ 1800F & 75psia.
(OP)
Any recommendations of a supplier for a valve under these conditions? Has anyone seen of these in the field?
I have been to several vendors and have currently found only one supplier - the shaft and stuffing box are air cooled.

The only thing I've seen that operates at your temperature is a damper working at few inches of water.

It will help if you know what materials will be acceptable for the process conditions.

Try Zimmermann & Jansen.

The butterfly valve is probably like a damper, as pointed out by unclesyd. I would visualize it as a swing thru disk fabricated steel castable lined butterfly valve.
Try suppliers Mader, Frischkorn, or Bloem Civieltechniek BV.

Keep the actuator well away from the line e.g. 12" otherwise the heat will effect the seals and allow for thermal expansion.
Too hot for Carbon steel, Stainless is better.
Good Luck

If you are not already speaking with some of the manufacturers listed above, you should be. If these guys have done it before, they know what won't work, too.
I suspect you will hear the word "Inconel" mentioned as a material, if not 347 Stainless.
Mounting the shaft horizontal will help keep the packing and the actuator out of the convected heat. You will need a pretty long extension, and a radiation shield is also a good idea just to keep radiant heat off the actuator.
Most heat gets to the actuator through the coupling. Stainless steel is a poor thermal conductor. Hence: Use a stainless coupling. An extra couple hundred dollars for Viton seals in the actuator is also worth it.
