Some try to "throttle" with a gate or ball valves
Globe valves are not the best for positive shut off, they are great under sinks .toilets and steam applications when you need a step down steam stations to control volume
A gate valve on high pressure steam will have the gate scored if used to throttle the steam entering a structure
Also using a gate causes turbulence when partially closed
I was a stationary engineer at 90 Church street and it was a hell of an education learning about central absorption systems and working on high pressure steam distribution
