Specifying a control valve without defining its allowable leakage rate is a recipe for operational disaster. When a valve is commanded to close, plant operators assume the flow of fluid stops completely. However, in the mechanical reality of industrial valves, “closed” rarely means a perfect, absolute seal. If a valve leaks slightly when closed, it might be acceptable in a cooling water bypass loop. But if that same valve leaks toxic chemicals or high-pressure steam, the consequences range from ruined product batches to catastrophic safety incidents. Engineers need a standardized, quantifiable method to define exactly how much leakage is acceptable for a specific application. The ANSI\/FCI 70-2 standard provides this […]<\/p>\n","protected":false},"author":2,"featured_media":1050,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":["post-1049","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-blog"],"acf":[],"_links":{"self":[{"href":"https:\/\/cartervalves.com\/ja\/wp-json\/wp\/v2\/posts\/1049","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/cartervalves.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/cartervalves.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/cartervalves.com\/ja\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/cartervalves.com\/ja\/wp-json\/wp\/v2\/comments?post=1049"}],"version-history":[{"count":2,"href":"https:\/\/cartervalves.com\/ja\/wp-json\/wp\/v2\/posts\/1049\/revisions"}],"predecessor-version":[{"id":1167,"href":"https:\/\/cartervalves.com\/ja\/wp-json\/wp\/v2\/posts\/1049\/revisions\/1167"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/cartervalves.com\/ja\/wp-json\/wp\/v2\/media\/1050"}],"wp:attachment":[{"href":"https:\/\/cartervalves.com\/ja\/wp-json\/wp\/v2\/media?parent=1049"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/cartervalves.com\/ja\/wp-json\/wp\/v2\/categories?post=1049"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/cartervalves.com\/ja\/wp-json\/wp\/v2\/tags?post=1049"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
