The  design  temperature  of  the  vessel  is  used  to  select  the  PR  valve  body  from  manufacturers'
temperature and pressure rating tables.  During relief the PR valve will be exposed to the emergency operating temperature which may be much higher than the vessel design temperature.  Nevertheless the PR valve body selection is not based on the emergency operating temperature since the emergency exposure is an infrequent, short-term stress.
