Good Morning All,

 

I would appreciate if anyone can advise here the acceptable set pressure tolerance and the standard used for testing PVRVs. I have done numerous research and all that I came across mentioned that allowable is +/- 10% for pressure/vacuum setting, however there is no document/standard to support same. I went through API2000, API 2521,API 576 & ISO 28300, but none of them mentioned the allowable tolerance. 

 

Thank you in advance for your cooperation and look forward to your response at your earliest convenience.

What does PVRVs stand for?

PVRV stands for pressure/vacuum relief valve. I guess "s" is a plural form?
