It is typically installed in industrial pipelines, connected on both sides by flanges. This design allows for safe use across different sections of the system. The disk inside the valve is rotated by a shaft, enabling the opening and closing of the valve.   <\/p>\n<p class=\"p1\">The disk is rotated according to the direction of the fluid flow, and a sealing gasket ensures a tight shutoff. Additionally, the valve body is designed to be integrated, providing long-term durability. It can be operated with manual, electric, or pneumatic actuators, offering flexibility in control and operation for different system needs.  <\/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\/double-flanged-butterfly-valve\/#How_Does_a_Double-Flanged_Butterfly_Valve_Work\" >How Does a Double-Flanged Butterfly Valve Work?<\/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\/double-flanged-butterfly-valve\/#Where_are_Flanged_Butterfly_Valves_Used\" >Where are Flanged Butterfly Valves Used?<\/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\/double-flanged-butterfly-valve\/#Flanged_Butterfly_Valve_Product_Features\" >Flanged Butterfly Valve Product Features<\/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\/double-flanged-butterfly-valve\/#Why_is_a_Double-Flanged_Butterfly_Valve_Preferred\" >Why is a Double-Flanged Butterfly Valve Preferred?<\/a><\/li><\/ul><\/nav><\/div>\n<h3><span class=\"ez-toc-section\" id=\"How_Does_a_Double-Flanged_Butterfly_Valve_Work\"><\/span><b>How Does a Double-Flanged Butterfly Valve Work?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p class=\"p1\">The disk inside the valve is rotated around a central shaft to control the flow. By rotating the disk 90 degrees, the valve is either fully opened or closed. This motion is based on a simple rotational principle. Sealing is achieved through EPDM or Viton seals.   <\/p>\n<p class=\"p1\">Control can be performed via a manual handle, gearbox, or an automation system. This allows the system to be safely managed without the need for remote intervention. Additionally, the low torque requirement helps in achieving energy savings.  <\/p>\n<h3><span class=\"ez-toc-section\" id=\"Where_are_Flanged_Butterfly_Valves_Used\"><\/span><b>Where are Flanged Butterfly Valves Used?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p class=\"p1\">Double-flanged butterfly valves are widely used across many industries.
