Especially valves used in high pressure and large diameter pipelines play a critical role in the efficient operation of the system. One of the prominent solutions at this point is <strong data-start=\"604\" data-end=\"635\">trunnion ball valves<\/strong>. So, what is a trunnion type ball valve and what advantages does it offer? We discuss it in detail in this article.    <\/p>\n<h2 class=\"\" data-start=\"752\" data-end=\"783\">What is a Trunnion Ball Valve?<\/h2>\n<p class=\"\" data-start=\"785\" data-end=\"1188\">A <strong data-start=\"785\" data-end=\"810\">trunnion ball valve<\/strong> is a special type of ball valve that has a rotating sphere inside and this sphere is supported on both sides. These support points are called <strong data-start=\"947\" data-end=\"961\">&#8220;trunnions&#8221;<\/strong>. Unlike standard floating ball valves, in trunnion type valves the sphere is fixed from above and below with supports fixed to the body. Thus, the sphere makes only rotational movement and no axial movement.   <\/p>\n<p class=\"\" data-start=\"1190\" data-end=\"1325\">Thanks to this structure, <strong data-start=\"1235\" data-end=\"1268\">it can work with lower torque<\/strong> even under high pressure, providing a more secure seal with less energy.<\/p>\n<h2 class=\"\" data-start=\"1332\" data-end=\"1349\"><img decoding=\"async\" class=\"alignnone wp-image-9739\" src=\"https:\/\/valve.tr\/wp-content\/uploads\/2025\/04\/trunnion-vana-1.png\" alt=\"\" width=\"600\" height=\"400\" srcset=\"https:\/\/valve.tr\/wp-content\/uploads\/2025\/04\/trunnion-vana-1.png 1536w, https:\/\/valve.tr\/wp-content\/uploads\/2025\/04\/trunnion-vana-1-300x200.png 300w, https:\/\/valve.tr\/wp-content\/uploads\/2025\/04\/trunnion-vana-1-1024x683.png 1024w, https:\/\/valve.tr\/wp-content\/uploads\/2025\/04\/trunnion-vana-1-768x512.png 768w, https:\/\/valve.tr\/wp-content\/uploads\/2025\/04\/trunnion-vana-1-900x600.png 900w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/h2>\n<h2 class=\"\" data-start=\"1332\" data-end=\"1349\">How does it work?<\/h2>\n<p class=\"\" data-start=\"1351\" data-end=\"1567\">Trunnion ball valves keep the sphere on a fixed axis thanks to the support spikes in its internal structure. The pressure generated by the fluid is transmitted to the trunnion supports , not directly to the sealing gaskets. In this way:  <\/p>\n<ul data-start=\"1569\" data-end=\"1692\">\n<li class=\"\" data-start=\"1569\" data-end=\"1613\">\n<p class=\"\" data-start=\"1571\" data-end=\"1613\">Sealing elements fatigue less,<\/p>\n<\/li>\n<li class=\"\" data-start=\"1614\" data-end=\"1639\">\n<p class=\"\" data-start=\"1616\" data-end=\"1639\">Torque requirement is reduced,<\/p>\n<\/li>\n<li class=\"\" data-start=\"1640\" data-end=\"1692\">\n<p class=\"\" data-start=\"1642\" data-end=\"1692\">A more secure structure is formed against high pressure.<\/p>\n<\/li>\n<\/ul>\n<h2 class=\"\" data-start=\"1699\" data-end=\"1735\">Advantages of Trunnion Ball Valve<\/h2>\n<h3 class=\"\" data-start=\"1737\" data-end=\"1775\">1. Resistant to High Pressure<\/h3>\n<p class=\"\" data-start=\"1776\" data-end=\"1927\">Trunnion structure provides a safe and stable flow control especially <strong data-start=\"1803\" data-end=\"1831\">in high pressure lines<\/strong>. There is no decrease in valve performance as the pressure increases. <\/p>\n<h3 class=\"\" data-start=\"1929\" data-end=\"1964\">2. Low Torque, High Efficiency<\/h3>\n<p class=\"\" data-start=\"1965\" data-end=\"2095\">It operates <strong data-start=\"1996\" data-end=\"2017\"> with lower torque<\/strong> than standard ball valves. This means advantages in terms of actuator selection and energy consumption. <\/p>\n<h3 class=\"\" data-start=\"2097\" data-end=\"2140\">3. Ideal for Large Diameter Lines<\/h3>\n<p class=\"\" data-start=\"2141\" data-end=\"2255\">It is one of the most reliable solutions in DN150 and above diameters, especially <strong data-start=\"2176\" data-end=\"2221\"> in oil, natural gas, water and energy lines<\/strong>.<\/p>\n<h3 class=\"\" data-start=\"2257\" data-end=\"2293\">4. Double Side Sealing<\/h3>\n<p class=\"\" data-start=\"2294\" data-end=\"2402\">Thanks to the two-way sealing gaskets, flow can be safely controlled from both directions.<\/p>\n<h3 class=\"\" data-start=\"2404\" data-end=\"2450\">5. Long Life and Low Maintenance<\/h3>\n<p class=\"\" data-start=\"2451\" data-end=\"2580\">The seals wear less because the ball movement is stabilized. This means <strong data-start=\"2540\" data-end=\"2564\">low maintenance costs<\/strong> for long-term use. <\/p>\n<h2 class=\"\" data-start=\"2587\" data-end=\"2619\">In which sectors is it used?<\/h2>\n<p class=\"\" data-start=\"2621\" data-end=\"2689\">Trunnion ball valves are widely preferred in the following sectors:<\/p>\n<ul data-start=\"2691\" data-end=\"2891\">\n<li class=\"\" data-start=\"2691\" data-end=\"2731\">\n<p class=\"\" data-start=\"2693\" data-end=\"2731\">?\ufe0f <strong data-start=\"2697\" data-end=\"2729\">Oil and gas transmission lines<\/strong><\/p>\n<\/li>\n<li class=\"\" data-start=\"2732\" data-end=\"2779\">\n<p class=\"\" data-start=\"2734\" data-end=\"2779\">? <strong data-start=\"2737\" data-end=\"2777\">Natural gas pressure reduction stations<\/strong><\/p>\n<\/li>\n<li class=\"\" data-start=\"2780\" data-end=\"2809\">\n<p class=\"\" data-start=\"2782\" data-end=\"2809\">\u2699\ufe0f <strong data-start=\"2785\" data-end=\"2807\">Power plants<\/strong><\/p>\n<\/li>\n<li class=\"\" data-start=\"2810\" data-end=\"2852\">\n<p class=\"\" data-start=\"2812\" data-end=\"2852\"><strong data-start=\"2815\" data-end=\"2850\">?
