They are critical safety devices used in industrial systems and equipment to prevent excessive pressure buildup. These valves automatically open when the pressure in the system exceeds a predetermined level, safely releasing the excess pressure. This prevents damage to the equipment and the surrounding environment.    <\/p>\n\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_83 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\/what-is-a-pressure-relief-valve-and-how-it-works\/#Operating_Principle_of_Pressure_Relief_Valves\" >Operating Principle of Pressure Relief Valves<\/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\/what-is-a-pressure-relief-valve-and-how-it-works\/#Applications_of_Pressure_Relief_Valves\" >Applications of Pressure Relief Valves<\/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\/what-is-a-pressure-relief-valve-and-how-it-works\/#Pressure_Relief_Valve_Selection_and_Maintenance\" >Pressure Relief Valve Selection and Maintenance<\/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\/what-is-a-pressure-relief-valve-and-how-it-works\/#Pressure_Relief_Valves_in_UNOX_Ovens\" >Pressure Relief Valves in UNOX Ovens<\/a><\/li><\/ul><\/nav><\/div>\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Operating_Principle_of_Pressure_Relief_Valves\"><\/span>Operating Principle of Pressure Relief Valves<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n<p class=\"wp-block-paragraph\">Pressure relief valves typically consist of a spring, a disc, and a body. The spring keeps the disc closed, maintaining the normal operating pressure. When the pressure in the system rises, it overcomes the spring force, pushing the disc upward and opening the valve. The opened valve releases the excess pressure, reducing the system pressure. Once the pressure returns to normal, the spring closes the disc again, and the valve shuts.    <\/p>\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Applications_of_Pressure_Relief_Valves\"><\/span>Applications of Pressure Relief Valves<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n<p class=\"wp-block-paragraph\">They are widely used in many industries where pressurized systems are present:<\/p>\n\n<ul class=\"wp-block-list\">\n<li>Chemical and Petrochemical Industry: For the safety of pressurized equipment such as reactors, tanks, and pipelines.<\/li>\n\n\n\n<li>Power Generation: To protect high-pressure systems such as boilers, turbines, and pipelines.<\/li>\n\n\n\n<li>Food and Beverage Industry: In hygienic applications such as pressurized vessels and sterilization equipment.<\/li>\n\n\n\n<li>HVAC Systems: For pressure control in heating, ventilation, and air conditioning systems.<\/li>\n\n\n\n<li>Marine Industry: For pressurized tanks and pipelines on ships.<\/li>\n<\/ul>\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Pressure_Relief_Valve_Selection_and_Maintenance\"><\/span>Pressure Relief Valve Selection and Maintenance<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n<p class=\"wp-block-paragraph\">The selection depends on the system&#8217;s operating pressure, temperature, fluid type, and other factors.
