Calculations for superheated steam safety valves

Recently, I am designing a steam distribution cylinder using superheated steam as the working medium; the design pressure is 1.65 MPa and the design temperature is 370°C, with two DN125 steam inlets... How should the safety valve be calculated?
What if the user insists on a safety valve?
Superheated steam is calculated as a gas, using the SW6 software and entering the parameters as required.
If the temperature is higher, the SW6 software does not allow the calculation to be performed.
I gave it a try; it’s possible to do the calculation, but the parameters for superheated steam aren’t fully available
There is a safety valve on the user condition diagram...
First, determine the leakage rate, then calculate the diameter using the fluid speed, and apply the pressure and temperature values in the calculations.
Upgrade this post and keep waiting for experts...
Determine the required diameter of the safety valve for calculating the discharge volume based on the intake pipe diameter and gas velocity in the pipeline.
