By adding the 0.1 bar shut-off margin, the safety valve set pressure has to be 10% greater than 6.4 bar. For this example, this means that the safety valves set pressure has to be: The set pressure would therefore be chosen as 7.11 bar, provided that this does not exceed the MAWP of the protected system.
