separate sealing and control stage Long Cage Plug
Multistage Reduction via cage plug. Noise damping by single and multistage controlled or uncontrolled silencer stages
It looks like an standard control valve with a parabolic cone. The Pressure drop is very high. It works with only one stage for the reduction.
Think about the water behind the Valve.
The Water get into Steam in a low Pressure area. Then the vapor condenses.
