The valve relies on the pressure of the pipeline medium flow to open or close the valve on its own. When the medium flows back, it is blocked by the valve disc and plays a role in preventing backflow. Compared with other valve products, this series is characterized by high temperature and high pressure resistance and a unique self-sealing design. The higher the pressure, the more reliable the sealing.<\/p>\n<p>&nbsp;<\/p>\n<p>Features<\/p>\n<p>\u2022 The shell is formed by casting or forging process, with smooth appearance and uniform structure, meeting the requirements of working conditions;<\/p>\n<p>\u2022 The valve disc adopts an internal hanging structure, with no external leakage points except for the self-sealing of the middle cavity, and the structure is compact;<\/p>\n<p>\u2022 The shaft and rocker adopt a multi-sliding pair design, and the surface of the shaft is treated with anti-corrosion treatment, which has good corrosion resistance and scratch resistance, eliminating the phenomenon of valve disc opening and closing jamming;<\/p>\n<p>\u2022 The sealing surfaces of the valve disc and valve seat are overlayed with STL carbide, which is resistant to high temperatures and provides a tight and reliable seal.<\/p>\n<p>&nbsp;<\/p>\n<p>Main design specifications<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-5957\" src=\"http:\/\/m.tenk.cn\/wp-content\/uploads\/2024\/03\/bf0491156d564d22977dacb48ec3536b.png\" alt=\"\" width=\"1015\" height=\"101\" srcset=\"http:\/\/www.zhengyuan-valve.com\/wp-content\/uploads\/2024\/03\/bf0491156d564d22977dacb48ec3536b-200x20.png 200w, http:\/\/www.zhengyuan-valve.com\/wp-content\/uploads\/2024\/03\/bf0491156d564d22977dacb48ec3536b-300x30.png 300w, http:\/\/www.zhengyuan-valve.com\/wp-content\/uploads\/2024\/03\/bf0491156d564d22977dacb48ec3536b-400x40.png 400w, http:\/\/www.zhengyuan-valve.com\/wp-content\/uploads\/2024\/03\/bf0491156d564d22977dacb48ec3536b-600x60.png 600w, http:\/\/www.zhengyuan-valve.com\/wp-content\/uploads\/2024\/03\/bf0491156d564d22977dacb48ec3536b-768x76.png 768w, http:\/\/www.zhengyuan-valve.com\/wp-content\/uploads\/2024\/03\/bf0491156d564d22977dacb48ec3536b-800x80.png 800w, http:\/\/www.zhengyuan-valve.com\/wp-content\/uploads\/2024\/03\/bf0491156d564d22977dacb48ec3536b.png 1015w\" sizes=\"(max-width: 1015px) 100vw, 1015px\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The main p [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":5956,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[327],"tags":[],"acf":[],"_links":{"self":[{"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=\/wp\/v2\/posts\/5955"}],"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=5955"}],"version-history":[{"count":1,"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=\/wp\/v2\/posts\/5955\/revisions"}],"predecessor-version":[{"id":5958,"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=\/wp\/v2\/posts\/5955\/revisions\/5958"}],"wp:featuredmedia":[{"embeddable":true,"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=\/wp\/v2\/media\/5956"}],"wp:attachment":[{"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=5955"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=5955"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=5955"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
