The sealing surface of the gate plate and valve seat is overlayed with STL carbide, which is high temperature resistant and has a tight and reliable seal;<\/p>\n<p>\u2022 Using a combination of braided and reinforced graphite packing, the compression nut is equipped with a pair of butterfly springs to continuously provide compression force and the valve stem seals reliably;<\/p>\n<p>\u2022 The pressure self-sealing part of the valve cover adopts an anti-ablation reinforced self-sealing ring, which can reliably seal at 650\u00b0C;<\/p>\n<p>\u2022 For gate valves used for main steam parameters, a self-sealing ring preloaded stud external structure is adopted to ensure the safe operation of the product under ultra-high temperature and high pressure conditions;<\/p>\n<p>\u2022 For the main steam working condition, the high-temperature material column bracket is used to improve the heat dissipation effect of the bracket, effectively reduce the temperature of the actuator, and improve the reliability of the valve;<\/p>\n<p>\u2022 For large-diameter main water supply gate valves, design inlet and outlet bypass valves to effectively reduce valve opening and closing torque.<\/p>\n<p>&nbsp;<\/p>\n<p>Main design specifications<\/p>\n<p><img decoding=\"async\" class=\"alignnone size-full wp-image-6054\" src=\"http:\/\/m.tenk.cn\/wp-content\/uploads\/2024\/03\/1f30ae8ef79d471d841c8372ddaa06b5.png\" alt=\"\" width=\"1016\" height=\"101\" srcset=\"http:\/\/www.zhengyuan-valve.com\/wp-content\/uploads\/2024\/03\/1f30ae8ef79d471d841c8372ddaa06b5-200x20.png 200w, http:\/\/www.zhengyuan-valve.com\/wp-content\/uploads\/2024\/03\/1f30ae8ef79d471d841c8372ddaa06b5-300x30.png 300w, http:\/\/www.zhengyuan-valve.com\/wp-content\/uploads\/2024\/03\/1f30ae8ef79d471d841c8372ddaa06b5-400x40.png 400w, http:\/\/www.zhengyuan-valve.com\/wp-content\/uploads\/2024\/03\/1f30ae8ef79d471d841c8372ddaa06b5-600x60.png 600w, http:\/\/www.zhengyuan-valve.com\/wp-content\/uploads\/2024\/03\/1f30ae8ef79d471d841c8372ddaa06b5-768x76.png 768w, http:\/\/www.zhengyuan-valve.com\/wp-content\/uploads\/2024\/03\/1f30ae8ef79d471d841c8372ddaa06b5-800x80.png 800w, http:\/\/www.zhengyuan-valve.com\/wp-content\/uploads\/2024\/03\/1f30ae8ef79d471d841c8372ddaa06b5.png 1016w\" sizes=\"(max-width: 1016px) 100vw, 1016px\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The main p [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":6053,"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\/6052"}],"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=6052"}],"version-history":[{"count":1,"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=\/wp\/v2\/posts\/6052\/revisions"}],"predecessor-version":[{"id":6055,"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=\/wp\/v2\/posts\/6052\/revisions\/6055"}],"wp:featuredmedia":[{"embeddable":true,"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=\/wp\/v2\/media\/6053"}],"wp:attachment":[{"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=6052"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=6052"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/www.zhengyuan-valve.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=6052"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
