Change Set Pressure of PRV
Change Set Pressure of PRV
(OP)
I have an existing PRV with set pressure at ~24 barg. This valve will be relocated to install in the new location with lower design pressure (non-U stamp vessel). The required new set pressure is ~10 barg. Should we consider to reuse this valve? I would like to order the new valve for such location. However, the management team requirement is utilizing of the existing valve.
The calculated orifice area for the new location is closed to the existing valve. However, I never change the set pressure of PRV in this range. Please comment.

In my understanding, after change the spring, both tightness test and pop test is necessary. If you have further comment, please inform me.
