How do I determine if a PSV will still be at maximum relief capacity if reset? There are two sets of PSVs, ones currently set at 500psig and need to be reset 475psig and ones that are set from 1210 to 1290 psig and need to be reset to 1100psig. I also have a PSV that is set at 445 psig and one that is at 600 psig that need to be reset to 475psig and 1100psig respectively but I didn’t know if they could be set higher than what it was rated for or if it just had to be replaced. The PSVs need to be able to relieve 6.2 mmcf.
