Read More7 Important Steps for Designing Pressure Reduction Valves
It is important to size a pressure reduction valve (PRV) to suit the flow rate that passes through it. You should not necessarily match the inlet pipe size as this can lead to over-sizing of the PRV and oversizing the PRV has adverse effects on the system such as causing undesired noise and also damaging the PRV seal.
