\u2014 It Is a Contact Mechanics Problem When a metal-seated butterfly valve fails to hold zero leakage after commissioning, the instinct is to blame the seat finish, the actuator torque setting, or the manufacturing tolerance. Those factors matter. But the underlying question is a physics one: is the contact stress at the disc-to-seat interface high enough, over a wide enough sealing band, to prevent fluid from finding a path through? The answer is governed by a 140-year-old theory from solid mechanics. When two curved surfaces are pressed together under load, the contact area, contact pressure distribution, and subsurface stress [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":1302,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":["post-1303","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\/1303","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=1303"}],"version-history":[{"count":1,"href":"https:\/\/cartervalves.com\/ja\/wp-json\/wp\/v2\/posts\/1303\/revisions"}],"predecessor-version":[{"id":1307,"href":"https:\/\/cartervalves.com\/ja\/wp-json\/wp\/v2\/posts\/1303\/revisions\/1307"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/cartervalves.com\/ja\/wp-json\/wp\/v2\/media\/1302"}],"wp:attachment":[{"href":"https:\/\/cartervalves.com\/ja\/wp-json\/wp\/v2\/media?parent=1303"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/cartervalves.com\/ja\/wp-json\/wp\/v2\/categories?post=1303"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/cartervalves.com\/ja\/wp-json\/wp\/v2\/tags?post=1303"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
