The stem rotates the ball, but the ball is not fixed by a lower trunnion support.<\/p>\n\n\n\n<p>When the valve is closed and upstream pressure increases, the ball moves slightly toward the downstream seat. This pressure-assisted movement pushes the ball against the downstream seat and creates the sealing contact.<\/p>\n\n\n\n<p>Key features of floating ball valves include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Simple structure:<\/strong> Fewer internal support components compared with a trunnion mounted design.<\/li>\n\n\n\n<li><strong>Compact body design:<\/strong> Suitable for small and medium-size piping systems where installation space matters.<\/li>\n\n\n\n<li><strong>Good shut-off performance:<\/strong> Reliable for many clean or moderately clean services when pressure, temperature, and seat material are correctly selected.<\/li>\n\n\n\n<li><strong>Cost efficiency:<\/strong> Usually more economical than a trunnion mounted ball valve in smaller sizes.<\/li>\n\n\n\n<li><strong>Easy maintenance:<\/strong> Simpler internal structure makes inspection, replacement, and repair easier in general service applications.<\/li>\n<\/ul>\n\n\n\n<p>Floating ball valves are widely used in water systems, compressed air lines, fuel gas lines, oil service, chemical utility lines, equipment packages, tank connections, and general industrial piping.<\/p>\n\n\n\n<p><strong>Engineering limitation:<\/strong> As valve size and pressure increase, the pressure force acting on the floating ball also increases. This raises the contact load between the ball and downstream seat, which can increase breakaway torque and accelerate seat wear. For this reason, floating ball valves should not be treated as a universal replacement for trunnion mounted ball valves in large-size or high-pressure service.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">What Is a Trunnion Mounted Ball Valve?<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">Definition and Key Features<\/h3>\n\n\n\n<p>A <strong>trunnion mounted ball valve<\/strong> uses a mechanically supported ball. The ball is fixed by trunnions, usually at the top and bottom, and rotates around a stable axis. Unlike a floating ball valve, the ball does not move downstream to create the main sealing force.<\/p>\n\n\n\n<p>In a trunnion mounted design, the seats move toward the fixed ball. Seat springs and line pressure help maintain sealing contact between the seat rings and the ball surface.<\/p>\n\n\n\n<p>Key features of trunnion mounted ball valves include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Fixed ball support:<\/strong> The trunnion structure carries pressure load and improves stability in large-size or high-pressure service.<\/li>\n\n\n\n<li><strong>Lower operating torque:<\/strong> Torque is usually more manageable than a floating ball valve in larger sizes and higher pressure classes.<\/li>\n\n\n\n<li><strong>Better suitability for automation:<\/strong> Lower and more stable torque supports gearbox, pneumatic, electric, or hydraulic actuator selection.<\/li>\n\n\n\n<li><strong>Pipeline service capability:<\/strong> Commonly used in oil and gas pipelines, gas transmission, refinery service, and petrochemical systems.<\/li>\n\n\n\n<li><strong>Optional DBB function:<\/strong> Many trunnion mounted designs can be supplied with double block and bleed features, depending on seat design and project requirements.<\/li>\n<\/ul>\n\n\n\n<p>Trunnion mounted ball valves are normally selected when size, pressure, safety, torque control, and long-term sealing reliability are more important than the lowest initial valve price.<\/p>\n\n\n\n<p>For pipeline and petroleum service, buyers may need to review standards such as <a href=\"https:\/\/www.api.org\/products-and-services\/standards\/important-standards-announcements\/spec6d\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">API 6D<\/a>, <a href=\"https:\/\/www.api.org\/-\/media\/Files\/Certification\/Monogram-APIQR\/0_API-Monogram-APIQR\/Advisories-Updates\/Updates\/API_Standard_608_7th_Edition_Update_20251006.pdf\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">API 608<\/a>, and <a href=\"https:\/\/www.asme.org\/codes-standards\/find-codes-standards\/b16-34-valves-flanged-threaded-welding-end\" target=\"_blank\" rel=\"noreferrer noopener nofollow\">ASME B16.34<\/a>.

After hydrostatic testing, operators found the valve difficult to open.<\/p>\n\n\n\n<p><strong>Cause:<\/strong> High differential pressure increased the load between the ball and downstream seat.

This helps create tight shut-off, but it also increases the contact force between the ball and seat.<\/p>\n\n\n\n<p>For small sizes and moderate pressure, this design works effectively. However, as valve size and pressure increase, the force acting on the ball becomes much larger. This can increase operating torque, seat compression, and wear during cycling.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Trunnion Mounted Ball Valve Sealing<\/h3>\n\n\n\n<p>In a trunnion mounted ball valve, the ball is fixed. The seat rings move toward the ball under spring force and pressure assistance. This design controls how the sealing load is applied and prevents the full pressure load from being carried only by the downstream seat.<\/p>\n\n\n\n<p>This is why trunnion mounted ball valves are preferred for larger sizes, higher pressure classes, gas pipelines, and critical isolation duties.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/raymonvalve.com\/wp-content\/uploads\/2026\/04\/6514-1024x683.png\" alt=\"Sealing principle of floating ball valve and trunnion mounted ball valve\" class=\"wp-image-12765\" title=\"\" srcset=\"https:\/\/raymonvalve.com\/wp-content\/uploads\/2026\/04\/6514-1024x683.png 1024w, https:\/\/raymonvalve.com\/wp-content\/uploads\/2026\/04\/6514-300x200.png 300w, https:\/\/raymonvalve.com\/wp-content\/uploads\/2026\/04\/6514-768x512.png 768w, https:\/\/raymonvalve.com\/wp-content\/uploads\/2026\/04\/6514-600x400.png 600w, https:\/\/raymonvalve.com\/wp-content\/uploads\/2026\/04\/6514.png 1536w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption><\/figcaption><\/figure>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><strong>Engineering note:<\/strong> Do not select the valve only by nominal size and pressure class.

As pressure and size increase, friction between the ball and seat increases. This means the torque required to open or close the valve also increases.<\/p>\n\n\n\n<p>In a trunnion mounted ball valve, the ball is supported by the trunnion structure. The seats move toward the ball, but the ball itself is not forced downstream in the same way.

Selecting Only by Valve Price<\/h3>\n\n\n\n<p>A floating ball valve may be cheaper, but it is not always suitable for large-size or high-pressure service. If torque, seat load, and pressure differential are ignored, the lower initial cost may become a maintenance problem later.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Ignoring Breakaway Torque<\/h3>\n\n\n\n<p>Breakaway torque is often higher than buyers expect, especially after the valve has stayed closed for a long time. This matters for both manual and automated valves.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Treating All Ball Valves as the Same<\/h3>\n\n\n\n<p>A small threaded floating ball valve and a large API 6D-type trunnion mounted pipeline ball valve are not interchangeable products. They may both be ball valves, but their design purpose is different.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Not Confirming Double Block and Bleed Requirements<\/h3>\n\n\n\n<p>Double block and bleed should not be assumed just because the valve is a ball valve. It depends on the valve design, seat configuration, body cavity design, and project specification.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Choosing the Seat Material Too Late<\/h3>\n\n\n\n<p>Seat material affects temperature limit, pressure capability, leakage performance, chemical compatibility, operating torque, and service life. It should be confirmed early, not after the valve body material has already been selected.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">6. Oversimplifying Actuator Selection<\/h3>\n\n\n\n<p>Actuator sizing should be based on real operating torque under service conditions, not only on nominal valve size. Differential pressure, seat type, operating frequency, safety factor, and fail position should all be reviewed.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">How to Choose Between Floating Ball Valve and Trunnion Mounted Ball Valve<\/h2>\n\n\n\n<p>Before choosing the valve type, confirm the actual service data.

What is the main difference between a floating ball valve and a trunnion mounted ball valve?<\/h3>\n\n\n\n<p>The main difference is the ball support structure. In a floating ball valve, the ball can move slightly under pressure and seals against the downstream seat. In a trunnion mounted ball valve, the ball is fixed by trunnions, and the seats move toward the ball to create sealing.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Which valve is better for high-pressure service?<\/h3>\n\n\n\n<p>A trunnion mounted ball valve is generally better for high-pressure service because the fixed ball structure reduces excessive seat load and helps maintain lower operating torque. The final selection should still confirm pressure class, seat material, end connection, leakage requirement, and project standard.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Is a floating ball valve suitable for gas service?<\/h3>\n\n\n\n<p>Yes, a floating ball valve can be used for gas service when the size, pressure, material, seat design, and testing requirements are suitable. For large-size or high-pressure gas pipelines, a trunnion mounted ball valve is usually preferred because torque and sealing stability become more important.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Why does a trunnion mounted ball valve have lower torque?<\/h3>\n\n\n\n<p>The ball is mechanically supported by trunnions, so it does not rely on pressure-driven downstream movement to create the main sealing force. This helps reduce friction between the ball and seat and keeps torque more stable in larger sizes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Which valve is more economical?<\/h3>\n\n\n\n<p>For small and medium-size general service, a floating ball valve is usually more economical. For large-size or high-pressure service, a trunnion mounted ball valve may provide better lifecycle value because of lower torque, better stability, and stronger suitability for demanding service.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">6. Can both floating and trunnion mounted ball valves be automated?<\/h3>\n\n\n\n<p>Yes. Both valve types can be automated with pneumatic or electric actuators. However, trunnion mounted ball valves are often more suitable for larger automated valves because their operating torque is lower and more predictable. Actuator sizing should be based on breakaway torque under actual differential pressure.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">7. Which ball valve should be used for oil and gas pipelines?<\/h3>\n\n\n\n<p>For oil and gas pipeline service, trunnion mounted ball valves are commonly selected, especially when the project involves high pressure, large size, API 6D-type requirements, double block and bleed, fire-safe design, or automated operation.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">8. Can a floating ball valve replace a trunnion mounted ball valve?<\/h3>\n\n\n\n<p>Only if the pressure, size, torque, sealing, seat material, operation method, and project specification allow it. A floating ball valve should not be used as a simple low-cost replacement for a trunnion mounted ball valve in critical pipeline service.<\/p>\n\n\n\n<p><\/p>","protected":false},"excerpt":{"rendered":"<p>Floating Ball Valve vs Trunnion Mounted Ball Valve: Key Differences and Selection Guide Choosing between a [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"set","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[190,1],"tags":[433,436,441,444,442,443,437],"class_list":["post-12762","post","type-post","status-publish","format-standard","hentry","category-ball-valve","category-news","tag-ball-valve-selection-guide","tag-floating-ball-valve","tag-floating-ball-valve-vs-trunnion-ball-valve","tag-high-pressure-ball-valve","tag-industrial-ball-valve","tag-pipeline-ball-valve","tag-trunnion-mounted-ball-valve"],"_links":{"self":[{"href":"https:\/\/raymonvalve.com\/pt\/wp-json\/wp\/v2\/posts\/12762","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/raymonvalve.com\/pt\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/raymonvalve.com\/pt\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/raymonvalve.com\/pt\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/raymonvalve.com\/pt\/wp-json\/wp\/v2\/comments?post=12762"}],"version-history":[{"count":1,"href":"https:\/\/raymonvalve.com\/pt\/wp-json\/wp\/v2\/posts\/12762\/revisions"}],"predecessor-version":[{"id":12768,"href":"https:\/\/raymonvalve.com\/pt\/wp-json\/wp\/v2\/posts\/12762\/revisions\/12768"}],"wp:attachment":[{"href":"https:\/\/raymonvalve.com\/pt\/wp-json\/wp\/v2\/media?parent=12762"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/raymonvalve.com\/pt\/wp-json\/wp\/v2\/categories?post=12762"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/raymonvalve.com\/pt\/wp-json\/wp\/v2\/tags?post=12762"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
