In these actuators, the piston moves in both directions with air, providing more controlled and balanced motion. They are commonly used in industrial automation systems, especially in applications where valves need to open and close quickly and precisely. Using air pressure in both directions instead of a spring contributes to the actuator\u2019s safe and stable operation.    <\/p>\n<p class=\"p1\">Double-acting pneumatic actuators developed by UNOX are offered as fully domestically produced devices. They are particularly effective for the automatic control of 90-degree rotary valves and dampers. These actuators are designed with high precision to enhance both system safety and efficiency.  <\/p>\n<p class=\"p1\">Double-acting systems not only allow the process to be stopped but also enable controlled changes in flow direction. This feature ensures maximum performance in process control systems. <\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_84 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-acting-pneumatic-actuator\/#Where_Are_Double-Acting_Pneumatic_Actuators_Used\" >Where Are Double-Acting Pneumatic Actuators 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\/double-acting-pneumatic-actuator\/#Cift_Etkili_Pnomatik_Aktuator_Genel_Ozellikleri\" >\u00c7ift Etkili Pn\u00f6matik Akt\u00fcat\u00f6r Genel \u00d6zellikleri<\/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-acting-pneumatic-actuator\/#Types_of_Control\" >Types of Control<\/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-acting-pneumatic-actuator\/#Construction_Details\" >Construction Details<\/a><\/li><\/ul><\/nav><\/div>\n<h3><span class=\"ez-toc-section\" id=\"Where_Are_Double-Acting_Pneumatic_Actuators_Used\"><\/span><b>Where Are Double-Acting Pneumatic Actuators Used?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p class=\"p1\">These types of actuators are widely preferred in many different fields, including the chemical industry, petrochemical plants, water and wastewater treatment systems, power plants, food processing facilities, and HVAC systems.
