In this system, two flaps are positioned symmetrically and operate automatically to prevent backflow. When flow begins, the flaps open, and when the flow stops, they close automatically with the help of spring support, effectively blocking reverse flow.  <\/p>\n<p class=\"p1\">Double-flap check valves are generally preferred for installation in horizontal pipelines. They are notable for their lightweight construction, low pressure drop, and compact design. Additionally, because the risk of water hammer is minimized in this type of valve, the connected system equipment is effectively protected from potential damage.  <\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_82_2 counter-hierarchy ez-toc-counter ez-toc-grey ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Sayfa \u0130\u00e7eri\u011fi<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/unox.com.tr\/en\/dual-plate-check-valve\/#Where_Are_Double_Flap_Check_Valves_Used\" >Where Are Double Flap Check Valves Used?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/unox.com.tr\/en\/dual-plate-check-valve\/#What_Are_the_Technical_Specifications\" >What Are the Technical Specifications?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/unox.com.tr\/en\/dual-plate-check-valve\/#Why_Are_Double-Disc_Check_Valves_Preferred\" >Why Are Double-Disc Check Valves Preferred?<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/unox.com.tr\/en\/dual-plate-check-valve\/#For_More_Information\" >For More Information<\/a><\/li><\/ul><\/nav><\/div>\n<h3><span class=\"ez-toc-section\" id=\"Where_Are_Double_Flap_Check_Valves_Used\"><\/span><b>Where Are Double Flap Check Valves Used?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p class=\"p1\">They have a wide range of applications, making them an indispensable part of industrial systems.

Additionally, thanks to the spring-assisted mechanism, the discs close more quickly, reducing the risk of water hammer.  <\/p>\n<p class=\"p1\">Thanks to its compact design, it can be easily installed in confined spaces, while maintenance requirements are kept to a minimum. All these advantages make double-disc check valves a popular choice for both new installations and upgrades to existing systems. <\/p>\n<h3><span class=\"ez-toc-section\" id=\"For_More_Information\"><\/span><b>For More Information<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p class=\"p1\">Information about check valve models specifically developed for different application requirements can be found under the<a href=\"https:\/\/unox.com.tr\/en\/valve-group\/\"> Unox Valve Category.<\/a><\/p>\n<p class=\"p1\">Additionally, the <a href=\"https:\/\/www.unoxonline.com.tr\/urun-kategori\/vana\/\" rel=\"nofollow noopener\" target=\"_blank\">Unox Online Catalog<\/a> can be visited to view products in detail and place orders.<\/p>\n<div id=\"attachment_59788\" style=\"width: 310px\" class=\"wp-caption alignnone\"><img decoding=\"async\" aria-describedby=\"caption-attachment-59788\" class=\"size-medium wp-image-59786\" src=\"https:\/\/unox.com.tr\/wp-content\/themes\/woodmart\/images\/lazy.svg\" data-src=\"https:\/\/unox.com.tr\/wp-content\/uploads\/2023\/08\/cift-klapeli-cekvalf-1-300x300.jpg\" alt=\"Dual Plate Check Valve\" width=\"300\" height=\"300\" title=\"\" srcset=\"\" data-srcset=\"https:\/\/unox.com.tr\/wp-content\/uploads\/2023\/08\/cift-klapeli-cekvalf-1-300x300.jpg 300w, https:\/\/unox.com.tr\/wp-content\/uploads\/2023\/08\/cift-klapeli-cekvalf-1-150x150.jpg 150w, https:\/\/unox.com.tr\/wp-content\/uploads\/2023\/08\/cift-klapeli-cekvalf-1-600x600.jpg 600w, https:\/\/unox.com.tr\/wp-content\/uploads\/2023\/08\/cift-klapeli-cekvalf-1-768x768.jpg 768w, https:\/\/unox.com.tr\/wp-content\/uploads\/2023\/08\/cift-klapeli-cekvalf-1.jpg 1000w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><p id=\"caption-attachment-59788\" class=\"wp-caption-text\">Dual Plate Check Valve<\/p><\/div>\n","protected":false},"excerpt":{"rendered":"<p><a href=\"https:\/\/unox.com.tr\/wp-content\/uploads\/2023\/08\/Cift-Klapeli-Cek-Valf.pdf\" target=\"_blank\" rel=\"noopener\"><button style=\"background-color: #11224b; color: #ffffff; padding: 10px 15px; font-family: montserrat; font-weight: bold; font-size: 19px; border-radius: 10px;\"><img decoding=\"async\" style=\"width: 25px; height: 25px;\" src=\"https:\/\/unox.com.tr\/wp-content\/uploads\/2023\/02\/pdf-1.png\">PRODUCT CATALOG<br \/>\n<\/button><\/a><\/p>\n<p><button style=\"background-color: #11224b; margin-top: 5px; color: white; padding: 0px 15px; width: 150px; height: 55px; border-radius: 10px; border: none; cursor: pointer;\"><br \/>\n<img decoding=\"async\" style=\"width: 120px; height: 30px;\" src=\"https:\/\/unox.com.tr\/wp-content\/uploads\/2023\/02\/4-1.svg\"><\/button><br \/>\n<br \/><a href=\"https:\/\/www.unoxonline.com.tr\/urun\/dual-cekvalf\/\" target=\"_blank\" rel=\"noopener\">Place an Online Order<br \/><\/a><button style=\"background-color: #11224b; color: #ffffff; padding: 10px 15px; font-family: montserrat; font-weight: bold; font-size: 19px; border-radius: 10px;\">UNOX<\/button><\/p>\n","protected":false},"featured_media":69314,"comment_status":"closed","ping_status":"closed","template":"","meta":{"_joinchat":[]},"product_brand":[],"product_cat":[1399,1129],"product_tag":[],"class_list":{"0":"post-57462","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-check-valves","7":"product_cat-valve-group","9":"first","10":"instock","11":"shipping-taxable","12":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/unox.com.tr\/en\/wp-json\/wp\/v2\/product\/57462","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/unox.com.tr\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/unox.com.tr\/en\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/unox.com.tr\/en\/wp-json\/wp\/v2\/comments?post=57462"}],"version-history":[{"count":1,"href":"https:\/\/unox.com.tr\/en\/wp-json\/wp\/v2\/product\/57462\/revisions"}],"predecessor-version":[{"id":68513,"href":"https:\/\/unox.com.tr\/en\/wp-json\/wp\/v2\/product\/57462\/revisions\/68513"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/unox.com.tr\/en\/wp-json\/wp\/v2\/media\/69314"}],"wp:attachment":[{"href":"https:\/\/unox.com.tr\/en\/wp-json\/wp\/v2\/media?parent=57462"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/unox.com.tr\/en\/wp-json\/wp\/v2\/product_brand?post=57462"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/unox.com.tr\/en\/wp-json\/wp\/v2\/product_cat?post=57462"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/unox.com.tr\/en\/wp-json\/wp\/v2\/product_tag?post=57462"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
