In this design of the valve, the stem crosses from the centerline of the disc. Between the pipe bore and the seat, there is the inside diameter boundary. This zero-offset valve is also called resilient-seated because it relies on the adaptability of the seat rubber to seal the flow after closing it efficiently. At around 85\u00b0 during a 90\u00b0 rotation, the disc first comes into connection with the seat in this kind of valve. Concentric butterfly valves are generally used for low-pressure applications.\r\n\r\n<!-- \/wp:paragraph -->\r\n\r\n<!-- wp:heading {\"level\":3} -->\r\n<h3>API 609 Category B Butterfly Valve<\/h3>\r\n<!-- \/wp:heading -->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nIn the eccentric butterfly valve, the stem passes behind the centerline of the disc instead of passing through it. As the stem is positioned behind the centerline, the valve is called a single offset. This design helps to minimize the disc contact with the seal, which increases the service life of the valve. In double-offset butterfly valves or doubly eccentric butterfly valves, the stem is positioned at the backside of the disc with an extra offset. This stem design allows the rotating disc to cover the seat only for one to three degrees. A triple offset butterfly valve is frequently used in more complex applications that have the same design as a double offset butterfly valve. A triple offset butterfly valve is efficient and reduces wear. This valve has metal seats that create a bubble-tight shut-off and make it able to use in higher temperature applications.\r\n\r\n<!-- \/wp:paragraph -->","parent":0,"count":9,"filter":"raw"},{"term_id":3159,"name":"api 609 cat a","slug":"api-609-cat-a","term_group":0,"term_taxonomy_id":3159,"taxonomy":"post_tag","description":"","parent":0,"count":2,"filter":"raw"},{"term_id":3157,"name":"api 609 cat b","slug":"api-609-cat-b","term_group":0,"term_taxonomy_id":3157,"taxonomy":"post_tag","description":"","parent":0,"count":2,"filter":"raw"},{"term_id":2628,"name":"API 609 Category A","slug":"api-609-category-a","term_group":0,"term_taxonomy_id":2628,"taxonomy":"post_tag","description":"","parent":0,"count":3,"filter":"raw"},{"term_id":2627,"name":"API 609 Category B","slug":"api-609-category-b","term_group":0,"term_taxonomy_id":2627,"taxonomy":"post_tag","description":"","parent":0,"count":3,"filter":"raw"},{"term_id":2630,"name":"API Butterfly Valve","slug":"api-butterfly-valve","term_group":0,"term_taxonomy_id":2630,"taxonomy":"post_tag","description":"","parent":0,"count":1,"filter":"raw"},{"term_id":3156,"name":"Butterfly Valve API 609","slug":"butterfly-valve-api-609","term_group":0,"term_taxonomy_id":3156,"taxonomy":"post_tag","description":"<!-- 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=\"mailto:commercial@zecovalve.com\" target=\"_blank\" rel=\"noopener noreferrer\"><strong>GET CHINA BUTTERFLY VALVE WITH HANDLES PRICELIST INFORMATION<\/strong><\/a>\r\n<!-- \/wp:generateblocks\/button -->\r\n<!-- \/wp:generateblocks\/button-container -->\r\n\r\n<!-- wp:kadence\/tableofcontents {\"uniqueID\":\"_983c00-2f\"} \/-->\r\n\r\n<!-- wp:paragraph -->\r\n\r\nButterfly valves are quarter-turn valves ideal for on\/off operations as well as modulating flow.
