Questions about safety valve pipeline settings

When disassembling the safety valve, drain the medium in the pipeline between the safety valve and the inlet valve.
This valve is generally used for confirmation/replacement before the safety valve goes offline for maintenance. Both gas and liquid phases must be set.
Pressure relief valve, safety valve used when calibrating
