It uses a rotating disc to stop, start, or regulate fluid flow through a pipeline.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Unlike gate or globe valves, the disc stays inside the flow path at all times. Its thin profile creates very little resistance when fully open.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Butterfly valves are widely used as <strong>valves for the chemical processing industry<\/strong>. They handle liquids, gases, slurries, and semi-corrosive media across diverse process conditions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Standard sizes range from 1 inch to over 200 inches in diameter. Pressure ratings typically run from 150 psi to 740 psi cold working pressure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Temperature capability depends on the seat material selected. Resilient-seated designs operate from -25\u00b0F to 300\u00b0F (ASME Class 150). High-performance designs extend up to 450\u00b0F. Metal-seated butterfly valves can withstand temperatures up to 1,000\u00b0F.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"The_Four_Core_Components_of_a_Butterfly_Valve\"><\/span><strong>The Four Core Components of a Butterfly Valve<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<figure class=\"wp-block-image size-large is-resized\"><img decoding=\"async\" width=\"1024\" height=\"512\" src=\"https:\/\/www.xintaivalves.com\/wp-content\/uploads\/2026\/06\/\u56fe\u724719-1024x512.webp\" alt=\"\u0686\u0647\u0627\u0631 \u062c\u0632\u0621 \u0627\u0635\u0644\u06cc \u0634\u06cc\u0631 \u067e\u0631\u0648\u0627\u0646\u0647\u200c\u0627\u06cc\" class=\"wp-image-15685\" style=\"width:606px;height:auto\" srcset=\"https:\/\/www.xintaivalves.com\/wp-content\/uploads\/2026\/06\/\u56fe\u724719-1024x512.webp 1024w, https:\/\/www.xintaivalves.com\/wp-content\/uploads\/2026\/06\/\u56fe\u724719-300x150.webp 300w, https:\/\/www.xintaivalves.com\/wp-content\/uploads\/2026\/06\/\u56fe\u724719-768x384.webp 768w, https:\/\/www.xintaivalves.com\/wp-content\/uploads\/2026\/06\/\u56fe\u724719-18x9.webp 18w, https:\/\/www.xintaivalves.com\/wp-content\/uploads\/2026\/06\/\u56fe\u724719.webp 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Each butterfly valve has the same four fundamental components. Understanding each one helps you select the right configuration for your specific chemical service.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><span class=\"ez-toc-section\" id=\"1_Body\"><\/span><strong>1. Body<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The valve body mounts directly between two pipe flanges. The two valve body configurations are wafer and lug type.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The wafer body sits between flanges and relies on flange bolts for compression. It costs less and transfers no pipe load through the valve.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The lug body has threaded bolt holes that match the pipe flange pattern. It supports dead-end service and allows downstream piping removal without disturbing the valve.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The valves\u2019 body materials include cast iron, ductile iron (ASTM A536), carbon steel (ASTM A216 WCB), and stainless steel (CF8M\/316). Material selection depends on fluid chemistry and operating temperature.<\/p>\n\n\n\n<h3 class=\"wp-block-heading has-medium-font-size\"><span class=\"ez-toc-section\" id=\"2_Disc\"><\/span><strong>2. \u062f\u06cc\u0633\u06a9<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The disc is the flow closure member of the valve. Rotating the valve to a quarter-turn fully opens or closes it. This is equivalent to a gate in a <a href=\"https:\/\/www.xintaivalves.com\/fa\/what-is-industrial-gate-valve\/\" target=\"_blank\" data-type=\"link\" data-id=\"https:\/\/www.xintaivalves.com\/what-is-industrial-gate-valve\/\" rel=\"noreferrer noopener\">\u0634\u06cc\u0631 \u062f\u0631\u0648\u0627\u0632\u0647<\/a> or a ball in a <a href=\"https:\/\/www.xintaivalves.com\/fa\/guide-to-industrial-ball-valve\/\" target=\"_blank\" data-type=\"link\" data-id=\"https:\/\/www.xintaivalves.com\/guide-to-industrial-ball-valve\/\" rel=\"noreferrer noopener\">\u0634\u06cc\u0631 \u062a\u0648\u067e\u06cc<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Disc geometry determines flow characteristics and operating torque. There are three profile designs common in chemical service.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">First is the concentric disc, which is<strong> <\/strong>center-mounted, low cost, and suitable for low-pressure service.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Second is the double-eccentric disc, which has an offset stem that reduces seat contact friction and extends seat service life.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Lastly, the triple-eccentric disc. Its near-zero opening friction is ideal for aggressive chemicals and temperatures up to 1,000\u00b0F.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"3_Stem\"><\/span><strong>3. Stem<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The stem transmits rotational torque from the actuator to the disc. It is available as a one-piece shaft or a two-piece split-stem assembly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In resilient-seated designs, the stem is fully isolated from the process fluid. This allows cost-effective carbon steel or stainless steel selection without sacrificing corrosion protection.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u0634\u06cc\u0631\u0647\u0627\u06cc

<\/strong>in industrial settings:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Butterfly valves require less space, labor, and piping support than equivalent gate or <a

\u0627\u06cc<\/a>.<\/li>\n\n\n\n<li>Fewer moving parts mean fewer wear points. This directly reduces maintenance intervals and unplanned downtime in continuous chemical processes.<\/li>\n\n\n\n<li>Butterfly valves are compatible with various materials such as PTFE, RTFE, and PFA. These linings resist corrosive chemicals, eliminating the need for costly alloy bodies.<\/li>\n\n\n\n<li>Non-wetted lined designs protect the body and stem from corrosive media. They deliver chemical resistance at a fraction of the cost of all-alloy valve construction.<\/li>\n\n\n\n<li>Quarter-turn operation integrates easily with DCS and PLC-based process control systems. This supports fully automated plant operations.<\/li>\n\n\n\n<li>Scalable from 1-inch to 200-inch diameters. A single valve family covers isolation needs across the entire chemical processing plant.<\/li>\n<\/ul>\n\n\n\n<style>\n  \/* Removed global HTML tags (body, head, etc.) to prevent WordPress theme conflicts *\/\n  .hero-card {\n    display: flex;\n    flex-wrap: wrap;\n    align-items: center;\n    background: #f7f8fa;\n    border-radius: 16px;\n    box-shadow: 0 6px 20px rgba(0, 0, 0, 0.05);\n    padding: 24px;\n    max-width: 900px;\n    margin: 40px auto;\n    font-family: 'Poppins', Arial, sans-serif;\n    text-decoration: none !important;\n    color: inherit;\n    transition: transform 0.3s ease, box-shadow 0.3s ease;\n  }\n\n  .hero-card:hover {\n    transform: translateY(-3px);\n    box-shadow: 0 10px 25px rgba(0, 0, 0, 0.1);\n  }\n\n  .hero-image {\n    width: 220px;\n    height: auto;\n    border-radius: 12px;\n    object-fit: contain; \/* Changed to contain to prevent cropping valve edges *\/\n    background: #ffffff;\n    flex-shrink: 0;\n  }\n\n  .hero-content {\n    padding-left: 24px;\n    flex: 1;\n    min-width: 260px;\n  }\n\n  .hero-title {\n    font-size: 1.6rem;\n    font-weight: bold;\n    margin-bottom: 12px;\n    color: #222;\n    font-family: 'Poppins', Arial, sans-serif;\n  }\n\n  .hero-description {\n    font-size: 1rem;\n    color: #555;\n    margin-bottom: 18px;\n    line-height: 1.6;\n  }\n\n  .hero-link {\n    display: inline-block;\n    padding: 10px 20px;\n    background-color: #D70C19;\n    color: #fff !important;\n    text-decoration: none !important;\n    border-radius: 8px;\n    font-weight: bold;\n    transition: background 0.2s ease-in-out;\n  }\n\n  .hero-link:hover {\n    background-color: #a80913; \/* Added a darker red for the hover state *\/\n  }\n\n  @media (max-width: 640px) {\n    .hero-card {\n      flex-direction: column;\n      text-align: center;\n    }\n    .hero-content {\n      padding-left: 0;\n      padding-top: 20px;\n    }\n    .hero-image {\n      width: 100%;\n      max-width: 280px;\n    }\n  }\n<\/style>\n\n<a class=\"hero-card\" href=\"https:\/\/www.xintaivalves.com\/fa\/butterfly-valve-collection\/\" target=\"_blank\" rel=\"noopener noreferrer\">\n  <img decoding=\"async\" class=\"hero-image\" src=\"https:\/\/xintaivalves.com\/wp-content\/uploads\/2022\/03\/%E6%9C%AA%E6%A0%87%E9%A2%98-2-1.jpg\" alt=\"\u0645\u062c\u0645\u0648\u0639\u0647 \u0634\u06cc\u0631\u0647\u0627\u06cc \u067e\u0631\u0648\u0627\u0646\u0647\u200c\u0627\u06cc \u0635\u0646\u0639\u062a\u06cc \u0628\u0631\u0627\u06cc \u06a9\u0646\u062a\u0631\u0644 \u0633\u06cc\u0627\u0644\u0627\u062a\">\n  <div class=\"hero-content\">\n    <div class=\"hero-title\">\u0645\u062c\u0645\u0648\u0639\u0647 \u0634\u06cc\u0631 \u067e\u0631\u0648\u0627\u0646\u0647 \u0627\u06cc<\/div>\n    <div class=\"hero-description\">\n      <strong>\u062a\u0627\u0628\u0639:<\/strong> \u06a9\u0646\u062a\u0631\u0644 \u062f\u0642\u06cc\u0642 \u062c\u0631\u06cc\u0627\u0646 \u0648 \u0645\u062f\u06cc\u0631\u06cc\u062a \u0633\u06cc\u0627\u0644\u0627\u062a.<br>\n      <strong>\u06a9\u0627\u0631\u0628\u0631\u062f:<\/strong> \u0645\u0647\u0646\u062f\u0633\u06cc \u0634\u062f\u0647 \u0628\u0631\u0627\u06cc \u062a\u0646\u0638\u06cc\u0645 \u0648 \u062c\u062f\u0627\u0633\u0627\u0632\u06cc \u0642\u0627\u0628\u0644 \u0627\u0639\u062a\u0645\u0627\u062f \u0633\u06cc\u0627\u0644 \u062f\u0631 \u062d\u0627\u0644 \u062c\u0631\u06cc\u0627\u0646 \u0627\u0632 \u0637\u0631\u06cc\u0642 \u0628\u062e\u0634 \u0647\u0627\u06cc \u062d\u06cc\u0627\u062a\u06cc \u062e\u0637\u0648\u0637 \u0644\u0648\u0644\u0647 \u0635\u0646\u0639\u062a\u06cc.\n    <\/div>\n    <span class=\"hero-link\">\u06a9\u0627\u0648\u0634 \u0645\u062c\u0645\u0648\u0639\u0647<\/span>\n  <\/div>\n<\/a>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span><strong>\u0646\u062a\u06cc\u062c\u0647<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Selecting the right <strong>chemical processing valves<\/strong> means understanding each component and how it works.
