[Steam-engine] Throttle valve

[Blake]

I believe there are different grades of ball valves - some have brass  
balls and seats and some have nylon seats, while some have stainless  
balls and seats. I would get one made for the highest pressure and  
with the most durable components. We have some 600 psi valves and  
some 2000 psi ball valves at work. I think I'd use the 2000 psi  
valves for what you are doing.
