{"id":65,"count":3,"description":"<p>Stainless steel check valves from a Taiwan manufacturer: swing type in 200 WOG PT threaded and JIS 10K \/ ANSI 150# flanged, plus a compact silent check valve. Sizes 1\/2\" to 4\".<\/p>\r\n<p>A check valve only has one job: let flow go one way and stop it coming back. Which type you need depends on how the line behaves when the pump stops.<\/p>\r\n<p>We stock three. The <strong>\u30b9\u30a4\u30f3\u30b0\u5f0f\u9006\u6b62\u5f01<\/strong> (316 cast stainless, ASTM A351 CF8M) has a hinged disc that opens with flow and drops shut when flow reverses. 200 WOG, PT threaded ends, 1\/2\" to 3\". The flanged check valve is the same swing principle in 304 stainless with flanged ends, rated JIS 10K \/ ANSI 150#, 2\" to 4\". The silent check valve is a one-piece compact body with an internal spring, threaded, 1\/2\" to 2\". The spring closes the disc as flow drops off, rather than waiting for the line to push it shut.<\/p>\r\n<p>All three are stainless steel.<\/p>\r\n<ul>\r\n<li><a href=\"https:\/\/ballvalves.tw\/ja\/%e8%a3%bd%e5%93%81\/%e3%81%ad%e3%81%98%e8%be%bc%e3%81%bf%e5%bc%8f%e9%80%86%e6%ad%a2%e5%bc%81\/\">Swing Check Valve, 200 WOG, PT Threaded<\/a> \u2014 316 cast stainless, 1\/2\" to 3\"<\/li>\r\n<li><a href=\"https:\/\/ballvalves.tw\/ja\/%e8%a3%bd%e5%93%81\/304%e3%83%95%e3%83%a9%e3%83%b3%e3%82%b8%e5%bc%8f%e9%80%86%e6%ad%a2%e5%bc%81\/\">Flanged Check Valve, JIS 10K \/ ANSI 150#<\/a> \u2014 304 stainless, 2\" to 4\"<\/li>\r\n<li><a href=\"https:\/\/ballvalves.tw\/ja\/%e8%a3%bd%e5%93%81\/%e7%84%a1%e9%9f%b3%e9%80%86%e6%ad%a2%e5%bc%81\/\">One-Piece Silent Check Valve<\/a> \u2014 304 stainless, threaded, 1\/2\" to 2\"<\/li>\r\n<\/ul>","link":"https:\/\/ballvalves.tw\/ja\/product-category\/check-valve\/","name":"\u30b9\u30c6\u30f3\u30ec\u30b9\u88fd\u9006\u6b62\u5f01","slug":"%e9%80%86%e6%ad%a2%e5%bc%81","taxonomy":"product_cat","parent":0,"meta":[],"menu_order":0,"_links":{"self":[{"href":"https:\/\/ballvalves.tw\/ja\/wp-json\/wp\/v2\/product_cat\/65","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ballvalves.tw\/ja\/wp-json\/wp\/v2\/product_cat"}],"about":[{"href":"https:\/\/ballvalves.tw\/ja\/wp-json\/wp\/v2\/taxonomies\/product_cat"}],"wp:post_type":[{"href":"https:\/\/ballvalves.tw\/ja\/wp-json\/wp\/v2\/product?product_cat=65"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
