How to Size a Full Flow PSV/PRV
How to Size a Full Flow PSV/PRV
(OP)
Hi,
I'm working on a job where I'm pumping oil into a pipeline using a positive displacement pump. I need to install a PRV downstream of the pump to kick in at the pipes MOP and divert the product upstream of the pump in an overpressure situation.
When calling the valve people we work with, they just asked me if the fluid was sour, what size (NPT) PRV I wanted, and what is the max pressure. Do I just have to wait until they set the valve to the pressure rating to see what the flow rate would be?
Thanks!

Btw, the Safety Relief Valve engineering (PSV) forum may have been a better choice for your post.

Of course you should also complete and issue a data sheet to make sure you get what you want, at which point you give them the data without it being misunderstood and allows for proper review and approval by others in your company as well....
