High temp (750-1000 F) valves?

[Begle1]

Anybody know of any electrically or pneumatically controlled ball or poppet valves good for 750-1000 degrees F steam?

I can't find any solenoid valves that say they're good, it seems like my best bet will be to put a rotary pneumatic actuator on a stainless steel ball valve...

Yes they use them in power generation plants. And they are very expensive.

Do they call them something special? What kind of seals or seats do they use?
