Its ease of operation also makes it the preferred choice. The chemical industry is one of those industries where the butterfly valves are required in abundance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">While making choices about the type of valve, many important factors should be considered by engineers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A <strong>pemprosesan kimia<\/strong><a href=\"https:\/\/www.xintaivalves.com\/ms\/butterfly-valve-collection\/\" target=\"_blank\" rel=\"noreferrer noopener\"><strong> injap rama-rama<\/strong><\/a> is vital in chemical processing.

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=\"Empat Komponen Teras Injap Rama-rama\" 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. Cakera<\/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\/ms\/what-is-industrial-gate-valve\/\" target=\"_blank\" data-type=\"link\" data-id=\"https:\/\/www.xintaivalves.com\/what-is-industrial-gate-valve\/\" rel=\"noreferrer noopener\">injap pagar<\/a> or a ball in a <a href=\"https:\/\/www.xintaivalves.com\/ms\/guide-to-industrial-ball-valve\/\" target=\"_blank\" data-type=\"link\" data-id=\"https:\/\/www.xintaivalves.com\/guide-to-industrial-ball-valve\/\" rel=\"noreferrer noopener\">injap bola<\/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\">High-performance butterfly valves expose the stem to the process media. The stem must meet both compatibility and mechanical strength requirements under seating loads.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"4_Seat\"><\/span><strong>4. Tempat Duduk<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The seat creates a tight seal between the disc edge and the valve body. It is the most chemically critical component in corrosive service applications.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Common seat materials and their key properties include the following:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>EPDM: <\/strong>suitable for water, steam, and mild chemical service up to 250\u00b0F.<\/li>\n\n\n\n<li><strong>NBR (Nitrile): <\/strong>compatible with oils and hydrocarbons, rated to 180\u00b0F.<\/li>\n\n\n\n<li><strong>PTFE \/ RTFE: <\/strong>broad chemical compatibility, rated from -40\u00b0F to 400\u00b0F, most common for chemical service.<\/li>\n\n\n\n<li><strong>PFA lining: <\/strong>yang <strong>PFA-lined butterfly valve for chemical processing<\/strong> fully encapsulates the body and stem. This isolates all metal parts from corrosive or ultra-pure media, eliminating the need for expensive alloy bodies.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">High-performance designs use line-energized seats, where pipeline pressure increases the sealing force. Fire-safe metal seat options provide shutoff integrity during and after thermal events (per API 607 \/ <a href=\"https:\/\/www.xintaivalves.com\/ms\/blog\/iso-10497-valve-fire-type-testing-requirements\/\" target=\"_blank\" data-type=\"link\" data-id=\"https:\/\/www.xintaivalves.com\/blog\/iso-10497-valve-fire-type-testing-requirements\/\" rel=\"noreferrer noopener\">ISO 10497<\/a> requirements).<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_Does_a_Butterfly_Valve_Work\"><\/span>Bagaimanakah Injap Rama-Rama Berfungsi?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">One of the reasons why a butterfly valve is in demand is due to its quick and simple operation. The 90-degree or quarter-turn action easily operates the valve to an open\/close position.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dalam posisi tertutup, cakram duduk tegak lurus terhadap arah aliran. Ia menghalangi seluruh lubang pipa dan mencegah aliran fluida.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Rotasi 90 derajat memindahkan cakram sejajar dengan jalur aliran. Ini menciptakan bukaan annular di sekitar tepi cakram, memungkinkan fluida melewatinya dengan resistansi minimal.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Profil cakram aerodinamis mengurangi turbulensi dan penurunan tekanan. Katup kupu-kupu lebih hemat energi daripada katup gerbang atau globe dalam aplikasi berdiameter besar.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Katup kupu-kupu mendukung layanan on-off dan layanan modulasi (throttling). Karakteristik aliran bergantung pada desain cakram dan jenis aktuator.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Persentase yang sama adalah karakteristik yang paling umum untuk aplikasi dosis kimia dan kontrol tekanan.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tipe linier lebih disukai ketika lebih dari 25% penurunan tekanan sistem tersedia di seluruh katup.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Tipe bukaan cepat digunakan untuk isolasi cepat. Ini jarang direkomendasikan untuk modulasi berkelanjutan.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Perhatikan bahwa katup kupu-kupu tidak berlubang penuh. Mereka tidak kompatibel dengan operasi pigging atau swabbing.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_are_the_Actuation_Methods_for_Chemical_Processing_Applications\"><\/span><strong>What are the Actuation Methods for Chemical Processing Applications?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Memilih aktuator yang tepat secara langsung memengaruhi keandalan proses dan biaya siklus hidup. Setiap metode aktuasi cocok untuk kondisi operasi yang berbeda.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Manual (roda tangan\/tuas\/operator roda gigi): <\/strong>cocok untuk operasi yang jarang dan katup di bawah DN 200.<\/li>\n\n\n\n<li><strong>Aktuator listrik: <\/strong>memberikan pemosisian yang tepat melalui sinyal kontrol 4-20 mA. Umum dalam sistem dosis kimia otomatis dan pemrosesan batch.<\/li>\n\n\n\n<li><strong>Aktuator pneumatik: <\/strong>menggunakan udara terkompresi bersih untuk respons cepat. Lebih disukai di pabrik kimia yang membutuhkan aktuasi ATEX atau tahan ledakan.<\/li>\n\n\n\n<li><strong>Aktuator hidrolik: <\/strong>menangani layanan berdiameter besar, bertekanan tinggi di mana torsi listrik atau pneumatik tidak mencukupi.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Katup kupu-kupu membutuhkan torsi operasi yang jauh lebih rendah daripada katup gerbang dengan ukuran yang setara. Ini mengurangi persyaratan ukuran aktuator dan menurunkan biaya sistem secara keseluruhan.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Why_Butterfly_Valves_Excel_in_Chemical_Processing\"><\/span><strong>Why Butterfly Valves Excel in Chemical Processing<\/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\u724720-1024x512.webp\" alt=\"Injap Rama-rama Cemerlang dalam Pemprosesan Kimia\" class=\"wp-image-15686\" style=\"width:630px;height:auto\" srcset=\"https:\/\/www.xintaivalves.com\/wp-content\/uploads\/2026\/06\/\u56fe\u724720-1024x512.webp 1024w, https:\/\/www.xintaivalves.com\/wp-content\/uploads\/2026\/06\/\u56fe\u724720-300x150.webp 300w, https:\/\/www.xintaivalves.com\/wp-content\/uploads\/2026\/06\/\u56fe\u724720-768x384.webp 768w, https:\/\/www.xintaivalves.com\/wp-content\/uploads\/2026\/06\/\u56fe\u724720-18x9.webp 18w, https:\/\/www.xintaivalves.com\/wp-content\/uploads\/2026\/06\/\u56fe\u724720.webp 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Pelbagai faktor teknikal dan komersial meletakkan injap rama-rama sebagai salah satu <strong>penyelesaian injap industri terbaik untuk loji pemprosesan kimia<\/strong>.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Berikut adalah kelebihan injap <strong>rama-rama pemprosesan kimia <\/strong>dalam tetapan industri:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Injap rama-rama memerlukan ruang, tenaga kerja, dan sokongan paip yang lebih sedikit berbanding injap gegata atau <a href=\"https:\/\/www.xintaivalves.com\/ms\/blog\/difference-between-gate-valve-and-globe-valve\/\" target=\"_blank\" data-type=\"link\" data-id=\"https:\/\/www.xintaivalves.com\/blog\/difference-between-gate-valve-and-globe-valve\/\" rel=\"noreferrer noopener\">injap glob<\/a>.<\/li>\n\n\n\n<li>Lebih sedikit bahagian bergerak bermakna lebih sedikit titik haus.
