The closing mechanism takes the form of a disk. Operation is similar to that of Ball Valves, which allows for quick shut-off. Butterfly valves are generally favored because they are lower in cost than other valve designs as well as being lighter in weight, meaning less support is required. The disc is positioned in the center of the pipe, passing through the disc is a rod connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, therefore a pressure drop is always induced in the flow, regardless of valve position.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:generateblocks\/button-container {\"uniqueId\":\"6d8495a3\",\"isDynamic\":true,\"blockVersion\":2} -->\r\n<!-- wp:generateblocks\/button {\"uniqueId\":\"3d442e11\",\"hasUrl\":true,\"target\":true,\"backgroundColor\":\"#0366d6\",\"textColor\":\"#ffffff\",\"backgroundColorHover\":\"#222222\",\"textColorHover\":\"#ffffff\",\"paddingTop\":\"15\",\"paddingRight\":\"20\",\"paddingBottom\":\"15\",\"paddingLeft\":\"20\"} -->\r\n<a class=\"gb-button gb-button-3d442e11 gb-button-text\" href=\"https:\/\/zecovalve.com\/contact\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>GET BUTTERFLY VALVE PRICE<\/strong><\/a>\r\n<!-- \/wp:generateblocks\/button -->\r\n<!-- \/wp:generateblocks\/button-container -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Types of Butterfly Valves<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:list -->\r\n<ul>\r\n \t<li><strong>Concentric Butterfly Valve<\/strong>\r\n<ul>\r\n \t<li>The most basic design of a butterfly valve is a centric or concentric butterfly valve. The stem passes through the disc\u2019s centerline, and the seat is the inside diameter periphery of the valve body (Figure 4 on the left). This zero-offset valve design is known as resilient-seated because efficient sealing relies on the flexibility of the rubber seat. When closing, the disc first comes into contact with the seat at around 85\u00b0 during a 90\u00b0 rotation. Concentric butterfly valves are suitable for low-pressure ranges.<\/li>\r\n<\/ul>\r\n<\/li>\r\n \t<li><strong>Double Offset Butterfly Valve<\/strong>\r\n<ul>\r\n \t<li>This popular valve is also known as a high-performance butterfly valve. This valve has two stems offset from the center. This creates a cam action during the application's process.<\/li>\r\n<\/ul>\r\n<\/li>\r\n \t<li><strong>Triple Offset Butterfly Valve<\/strong>\r\n<ul>\r\n \t<li>Triple Offset Butterfly Valves are essential in applications where a bubble-tight shut-off is required. In some applications, bubble-tight shut-off cannot be achieved using double offset butterfly valves. Some applications do not lend themselves well to traditional butterfly valves, for example, applications involving harsh chemicals or media with small particles prone to clogging valves and pipelines.<\/li>\r\n<\/ul>\r\n<\/li>\r\n<\/ul>\r\n<!-- \/wp:list -->\r\n\r\n<!-- wp:heading -->\r\n<h2>Gate Valve vs Butterfly Valve<\/h2>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nButterfly valves are comparatively more extensively used in large sizes compared to gate valves. Because butterfly valves open and close quickly and can be frequently operated, they are ideal for applications that require quick opening and closing, especially for emergency shutoffs.\r\n\r\n<!-- \/wp:paragraph -->","parent":0,"count":11,"filter":"raw"}],"taxonomy_info":{"category":[{"value":1,"label":"Uncategorized"}],"post_tag":[{"value":1881,"label":"Butterfly Valve Wikipedia"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v15.4 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Eccentric Butterfly Valve Installation Direction and Other Common Problems - ZECO Valve<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/zecovalve.com\/pt\/eccentric-butterfly-valve-installation-direction-and-other-common-problems.html\" \/>\n<meta property=\"og:locale\" content=\"pt_PT\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Eccentric Butterfly Valve Installation Direction and Other Common Problems - ZECO Valve\" \/>\n<meta property=\"og:description\" content=\"Before installing the eccentric butterfly valve, pay attention to the sealing direction.
