Gate Valve PR2 requirements
(OP)
Question on API 6A Gate valve PR2 qualification requirements;
if the requirement is to develop just a PR2 Gate valve without the mention of Annex F, does the valve still need to qualify Annex F temperature cycles?
or, does it qualify to be sold as PR2 by meeting 200 ambient seat test cycles as per section 10.5.2 of API 6A 20th edition?
Please advise.

RE: Gate Valve PR2 requirements
Many purchasers seem to assume that PR2 also means Annex F. This is incorrect, but it is a common misconception, and it would be a good idea to discuss with your customer.
