Safety valve will operate in vapor or steam line. Relief
will operate both in liquid and vapor line. safety valve
will lift when the set pressure reaches and will sit after
it reaches the preset pressure. Mostly safety valves are
not hunting due to difference between lift and sit
pressures are more. But relief valve will lift to discharge
the excess pressure and sit back immediately. relief valves
are mostly hunting.
