Using advanced die forging technology, the company produces valve bodies with a dense metal structure that effectively eliminates casting defects such as porosity and inclusions, thereby enhancing strength and pressure-bearing capacity.<\/span><\/p>\n<p class=\"ds-markdown-paragraph\"><span class=\"\">\u00a0 The sealing faces are overlaid with Stellite hard alloy and then mirror-finished through a multi-step lapping process. This ensures excellent sealing performance under high-temperature, high-pressure, and corrosive media. Following GB\/T 13927 standards, each valve undergoes 100% shell strength testing at 1.5 times the rated pressure and seat leakage testing. With pressure ratings from 150Lb to 2500Lb and temperature ranges from -196\u00b0C to 800\u00b0C, these forged steel gate, globe, check, and ball valves are widely used in petrochemical, power, and other critical industries.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u00a0 Zhengyua [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[61],"tags":[],"acf":[],"_links":{"self":[{"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=\/wp\/v2\/posts\/9651"}],"collection":[{"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=9651"}],"version-history":[{"count":1,"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=\/wp\/v2\/posts\/9651\/revisions"}],"predecessor-version":[{"id":9652,"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=\/wp\/v2\/posts\/9651\/revisions\/9652"}],"wp:attachment":[{"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=9651"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=9651"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=9651"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
