How should the setting pressure of the safety valve on the outlet pipeline of a reciprocating pump be determined?

I’m seeking advice from everyone: how is the setting pressure for the safety valve on the outlet pipeline of a reciprocating pump determined? Thank you! !
Check whether the safety valve installed at the outlet of the reciprocating pump is intended to protect downstream equipment or to protect the reciprocating pump itself. If it is to protect the pump itself, then a design pressure that has been confirmed by the pump manufacturer is required ； If it is to protect downstream equipment, the design pressure of the equipment can be determined. Generally, the setting pressure of the safety valve at the outlet of the reciprocating pump is determined based on the design pressure of the downstream equipment, which should be sufficient to meet the safety requirements of both the pump and the downstream equipment.
I hadn’t been exposed to it before; now I’m learning it*
Protecting downstream equipment is not appropriate; the selection of pumps and piping should prevent overpressure under normal operating conditions.
