Knowing this operating principle helps you match the valve to the right service condition.\u00a0<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This zero-offset configuration features three components aligned on a single central axis: the stem, the disc, and the valve body. Because this concentric alignment serves as its defining structural feature, it is classified as a concentric or zero-offset butterfly valve.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The disc mounts on a centered shaft and sits directly in the flow path. Rotating the shaft 90 degrees moves the disc from fully open (parallel to flow) to fully closed (perpendicular to flow).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At the closed position, the disc compresses against a resilient elastomeric seat ring. The seat ring deforms slightly under pressure. This elastic deformation creates a bubble-tight seal that prevents leakage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This elastic deformation yields a bubble-tight, zero-leakage bi-directional shut-off certified to API 598 testing standards. It is also known as a resilient seated butterfly valve because of this elastomeric seat design.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Types_of_Centric_Butterfly_Valves_by_End_Connection\"><\/span><strong>U\u00e7 Ba\u011flant\u0131s\u0131na G\u00f6re Merkezli Kelebek Vana Tipleri<\/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\u724723-1024x512.webp\" alt=\"U\u00e7 Ba\u011flant\u0131s\u0131na G\u00f6re 3 Tip Merkezcil Kelebek Vana\" class=\"wp-image-15692\" style=\"width:646px;height:auto\" srcset=\"https:\/\/www.xintaivalves.com\/wp-content\/uploads\/2026\/06\/\u56fe\u724723-1024x512.webp 1024w, https:\/\/www.xintaivalves.com\/wp-content\/uploads\/2026\/06\/\u56fe\u724723-300x150.webp 300w, https:\/\/www.xintaivalves.com\/wp-content\/uploads\/2026\/06\/\u56fe\u724723-768x384.webp 768w, https:\/\/www.xintaivalves.com\/wp-content\/uploads\/2026\/06\/\u56fe\u724723-18x9.webp 18w, https:\/\/www.xintaivalves.com\/wp-content\/uploads\/2026\/06\/\u56fe\u724723.webp 1200w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">There are three main end connection types that serve different installation and service needs.

The valve body has no integral flanges. This keeps the design compact and lightweight.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The wafer type is the most cost-effective option for general service. Standard <strong>wafer TYPE butterfly valve Dimensions<\/strong> follow API 609, BS EN 558-1, and ASME B16.10.
