It is widely used in chemical industry, electric power, light textile, food, medicine, paper and other industrial sectors, as well as municipal engineering, water plants and other pipelines to cut off or adjust the flow control of tap water, sewage, oil liquid or air, gas, natural gas, water vapor medium.<\/p>\n<p><strong>Features:<\/strong><br \/>\nThe valve body adopts integral casting technology, which is compact in structure, small in size and light in weight;<br \/>\nThe valve plate is installed eccentrically, and when closed, the valve plate expands outward to achieve a good peripheral sealing state; When opened, the valve plate and the sealing ring are quickly disengaged, effectively preventing the wear of the sealing ring;<br \/>\nThe design of the sealing ring is novel, concise and maintenance-free;<br \/>\nThe sealing ring form is available in two types: soft seal and metal seal to meet the requirements of different working conditions.<br \/>\nDue to the eccentric structure, the operating torque is greatly reduced;<br \/>\nThe flow resistance is small, and the forehead flow coefficient is large, which is about 3 times that of single-seat valves of the same caliber.<br \/>\nStrong self-cleaning ability and long service life;<br \/>\nThe valve adopts a column flange structure, and the process pipeline adopts a clip-on type installation;<br \/>\nThe three types of standard actuators (pneumatic piston, pneumatic membrane and electric) are interchangeable.<\/p>\n<p><strong>Part material<\/strong><br \/>\nMain parts materials<br \/>\nValve body: ZG230-450, ZG1Cr18Ni9Ti<br \/>\nValve plate: ZG1Cr18Ni9Ti<br \/>\nValve shaft: 3Cr13, ZG1Cr18Ni9Ti<br \/>\nPressing ring: ZG230-450, 1Cr18Ni9Ti<br \/>\nSealing ring: reinforced PTFLON, 0Cr18Ni9Ti, 17-4PH<br \/>\nFillers: Teflon, flexible graphite<br \/>\nGuide sleeve: QA19-4, 0Cr18Ni9, composite material<br \/>\nBracket: ZG230-450<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u54c1\u724c\uff1a\u91d1\u5965<\/p>\n<p>\u578b\u53f7\uff1a ZMAW,ZSHW,ZSHWB,ZDRW,ZDRWB<\/p>\n","protected":false},"author":1,"featured_media":871,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_et_pb_use_builder":"","_et_pb_old_content":"","_et_gb_content_width":"","footnotes":""},"categories":[75,7],"tags":[],"class_list":["post-1697","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-df-en","category-products"],"_links":{"self":[{"href":"https:\/\/www.jinaovalve.com\/index.php?rest_route=\/wp\/v2\/posts\/1697","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.jinaovalve.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.jinaovalve.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.jinaovalve.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.jinaovalve.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=1697"}],"version-history":[{"count":2,"href":"https:\/\/www.jinaovalve.com\/index.php?rest_route=\/wp\/v2\/posts\/1697\/revisions"}],"predecessor-version":[{"id":1705,"href":"https:\/\/www.jinaovalve.com\/index.php?rest_route=\/wp\/v2\/posts\/1697\/revisions\/1705"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.jinaovalve.com\/index.php?rest_route=\/wp\/v2\/media\/871"}],"wp:attachment":[{"href":"https:\/\/www.jinaovalve.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=1697"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.jinaovalve.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=1697"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.jinaovalve.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=1697"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
