Boiler Mountings - MarinersPoint - Boiler Mountings

Safety Valve generally used are of Spring loaded safety valve. In case of unsafe excess pressure inside the boiler, the security valve is used to release the excess pressure. Before installation, the valve's lifting pressure is set and locked in the presence of a surveyor so that it does not change later.

Safety Valve Selection | Spirax Sarco

This arrangement is suitable if the pump-trap motive pressure is less than 1.6 bar g (safety valve set pressure of 2 bar g less 0.3 bar blowdown and a 0.1 bar shut-off margin). Since the MAWP of both the APT and the vessel are greater than the safety valve set pressure, a single safety valve would provide suitable protection for the system.
