Step-down pressure of demin water line
Step-down pressure of demin water line
(OP)
I am looking for options to reduce the demin water pressure from a 8 barg header to about 5 barg for a downstream process unit. The downstream unit has been designed to work with a low pressure rating and there is a relief valve set at 5.5 barg. Anybody got any sugestions on what can be used to do that? Thanks.

Do you need to reduce the operating pressure? Are you trying to prevent the PSV from opening?
I don't know what your flowrate is to the lower pressure system but a control valve would be a pretty common solution. The dP across an RO will vary as the flow rate changes. The dP is likely too low for a hydraulic recovery turbine. We really need some more information on your system and what you are trying to achieve.
