This part of ISO 4126 specifies the sizing of safety valves for gas/liquid two-phase flow in pressurized systems
such as reactors, storage tanks, columns, heat exchangers, piping systems or transportation tanks/containers.
The possible fluid states at the safety valve inlet that can result in two-phase flow are given in Table 1.
NOTE The expression “safety valve” is a synonym for valves as described in ISO 4126-1, ISO 4126-4 and ISO 4126-5.
