metal-seated butterfly valve and a soft-seated butterfly valve is crucial. Choosing the wrong sealing material can lead to premature leaks, costly unplanned shutdowns, and serious safety risks.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This article discusses the differences between metal-seated and soft-seated valves, their features, specifications, and applications. It will help engineers and procurement buyers to decide on valve types based on ISO 5208 standards.\u00a0<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Soft_Seated_Butterfly_Valves_Features_and_Specifications\"><\/span>\u0634\u06cc\u0631\u0647\u0627\u06cc \u067e\u0631\u0648\u0627\u0646\u0647\u200c\u0627\u06cc \u0628\u0627 \u0646\u0634\u06cc\u0645\u0646 \u0646\u0631\u0645: \u0648\u06cc\u0698\u06af\u06cc\u200c\u0647\u0627 \u0648 \u0645\u0634\u062e\u0635\u0627\u062a<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A soft-seated butterfly valve uses an elastic, non-metallic material for the sealing surface. When the disc closes, it presses against the soft seal. That\u2019s why it\u2019s called a soft-seated valve.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The valve\u2019s material deforms slightly and fills the microscopic gaps between the disc edge and seat. This results in a tight, zero-leakage seal.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This design is also evident in the resilient seated <strong>butterfly control valve<\/strong>. Another type is the <strong>bonded seat butterfly valve,<\/strong> where the seat is bonded directly inside the body during manufacturing. This design construction renders the seat inseparable from the body. It helps reduce assembly parts, but also means you have to replace the body when the seat wears out.\u00a0<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Common_Materials_Used_in_Soft_Seat_Valves\"><\/span>\u0645\u0648\u0627\u062f \u0631\u0627\u06cc\u062c \u0645\u0648\u0631\u062f \u0627\u0633\u062a\u0641\u0627\u062f\u0647 \u062f\u0631 \u0634\u06cc\u0631\u0647\u0627\u06cc \u0646\u0634\u06cc\u0645\u0646 \u0646\u0631\u0645<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This section discusses the different materials and technical specifications used in soft seat valves. Each material suits different media, which depend on temperature, chemical compatibility, and how often the valve cycles.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>EPDM (Ethylene Propylene Diene Monomer) \u2013 <\/strong>Resists ozone, heat, and aging. Can operate in temperatures from -40\u00b0C to 120\u00b0C. Used in freshwater, wastewater, and seawater systems.<\/li>\n\n\n\n<li><strong>NBR (Nitrile\/Buna-N) \u2013 <\/strong>Standard choice for petroleum-based fluids and natural gas service. Good oil and abrasion resistance. Can operate in temperatures ranging from -30\u00b0C to 90\u00b0C.<\/li>\n\n\n\n<li><strong>PTFE (Polytetrafluoroethylene) \u2013 <\/strong>Has near-universal chemical resistance. Typically used in pharmaceutical, chemical, and acid\/alkali pipelines. Available in FDA-compliant grades.
