Here is a link of the mollier chart showing that when you go through the PRV and enthalpy stays the same you move into the "wet steam region". Just as MisterDonut said it...
I am trying to determine the temperature of the steam after it goes through a pressure reducing valve (prv).
The upstream pressure is 600 psig @ saturation temperature. The down stream pressure is 400 psig.
From my understanding going through a prv the enthalpy of the system should stay the...
