Thanks to its single-acting design, it operates by applying air pressure in only one direction. The return movement is performed automatically by a spring mechanism. This feature ensures that the valve returns to the closed position in the event of system failures.   <\/p>\n<p class=\"p1\">Inside the valve, there is a ball made of U-PVC material that directs the flow. This ball is rotated 90 degrees by the actuator to move between the open and closed positions. U-PVC material is preferred due to its chemical resistance and lightweight structure. As a result, high performance is achieved at a low cost.   <\/p>\n<p class=\"p1\">The actuator system is supported by a low-friction piston and pinion mechanism. This allows the valve opening and closing operations to be completed with minimal energy. It operates solely with compressed air, without the need for any electrical connection. Therefore, it offers safe operation in environments with a risk of explosion.   <\/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\/pneumatic-actuated-u-pvc-ball-valve-single\/#Where_Is_a_Pneumatically_Actuated_U-PVC_Ball_Valve_Used\" >Where Is a Pneumatically Actuated U-PVC Ball Valve 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\/pneumatic-actuated-u-pvc-ball-valve-single\/#Technical_Specifications_and_Actuator_Information\" >Technical Specifications and Actuator Information<\/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\/pneumatic-actuated-u-pvc-ball-valve-single\/#Construction_Features\" >Construction 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\/pneumatic-actuated-u-pvc-ball-valve-single\/#Advantages_of_U-PVC_Ball_Valves\" >Advantages of U-PVC Ball Valves<\/a><\/li><\/ul><\/nav><\/div>\n<h3><span class=\"ez-toc-section\" id=\"Where_Is_a_Pneumatically_Actuated_U-PVC_Ball_Valve_Used\"><\/span><b>Where Is a Pneumatically Actuated U-PVC Ball Valve Used?<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p class=\"p1\">These types of valves are widely used in water treatment plants for automatic flow control.
