API Standard 594 covers design, material, face-to-face dimensions, pressure-temperature ratings, and examination, inspection, and test requirements for two types of check valves.The definitons below are from engineeringtoolbox. API600 would appear to be for gate valves? •ANSI/API 600 Bolted Bonnet Steel Gate Valves for Petroleum and Natural Gas Industries - Modified National Adoption of ISO 10434:1998. •ANSI/API STD 594 Check Valves: Flanged, Lug, Wafer and Butt-welding. API Standard 594 covers design, material, face-to-face dimensions, pressure-temperature ratings, and examination, inspection, and test requirements for two types of check valves. "Sharing knowledge is the way to immortality" His Holiness the Dalai Lama. waterhammer.hopout.au/Technically API 600 is only a gate valve spec. However most of the industry incorrectly refers to it when specifying checks and globes. API 594 should be used for check valves. For the most part it is the API 600 of check valves however it has a couple odd manufacturing requirements that many standard designs do not meet (ex. limits on disc rotation) so therefore it seems to not get invoked very often. So what what most people really want is a check valve that meets the "applicable parts" of API 600 which generically means Wall thickness, trim materials, etc. API is currently developing API 623 which will be for globe valves. Currently API has no globe valve standardyah, I participate with the process of developing that new spec, now i am just worried that this would become another "594" where it's there, but no one bother to make or demand it. I know a couple major companies would just plainly put API 600 check valve on their catalogue, and googling api 594 swing check would turn up only misc Chinese manufacturers. I even had end-users demanding me to put API 600 on the drawings of our check valves as design standards. the exact differences between API 594 swing and BS 1868 are as follow. 1) disc nut must be positively secured 2) disc must not swivel 360 degrees 3) top bonnet/cap must be calculated per ASME PBV VIII UG34 and UG35. which can yield more stringent requirement when compared to BS 1868 w/ API 600 wall thickness. So I guess really the question is, anyone, here, EVER, bought, requested, provided API 594 type B swing check valve? Seems like a dead spec to me =/1No doubt there are many consultants out there who list every standard they come across in their specifications without knowledge of the content. In my 40+ years in the business I have come across such ignorance so often accompanied by the words that the contractor "shall comply with most ardous conditions" in any of the standards. From a legal perspective this cannot be enforced as the provision is too wide and embracing. Also the matter of "in contra preferentum" applies. en.wikipedia.org/wiki/Contra_proferentem So if you are one of those silly engineers who thinks they are protecting their client or that they will get a better product by such actions I suggest your read the above article. Before specifying a standard you, the enginner, needs to understand what that standard covers. "Sharing knowledge is the way to immortality" His Holiness the Dalai Lama. waterhammer.hopout.au/Here is one example of a Type B to API 594 from a reputable manufactuer. ht tp://k itzus-kca. com/pdf/ch eck_low/ch eck150.pdf Check Valves: Flanged, Lug, Wafer, and Butt-welding SEVENTH EDITION | SEPTEMBER 2010 | 21 PAGES PRICE: $102.00 | PRODUCT NO.
