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\r\n\r\n\r\nAPI 609 Category B Butterfly Valve<\/h3>\r\n\r\n\r\n\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","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":"\r\n\r\nGET CHINA BUTTERFLY VALVE WITH HANDLES PRICELIST INFORMATION<\/strong><\/a>\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nButterfly valves are quarter-turn valves ideal for on\/off operations as well as modulating flow.

V\u00e1lvulas de mariposa con clasificaci\u00f3n de presi\u00f3n y temperatura que tienen un asiento desplazado y una configuraci\u00f3n de disco exc\u00e9ntrica o conc\u00e9ntrica. Estas v\u00e1lvulas pueden tener una clasificaci\u00f3n de asiento menor que la clasificaci\u00f3n del cuerpo. Los tama\u00f1os cubiertos son NPS 3 a NPS 24 para las clases 150, 300 y 600.<\/p>\n\n\n\n
La v\u00e1lvula de mariposa Clase B de la norma API 609 especifica la longitud de la estructura de la v\u00e1lvula de mariposa est\u00e1ndar estadounidense, la v\u00e1lvula de mariposa de brida y la v\u00e1lvula de mariposa de orejeta. En comparaci\u00f3n con la v\u00e1lvula de mariposa GB est\u00e1ndar nacional, la v\u00e1lvula de mariposa de brida y la v\u00e1lvula de mariposa est\u00e1ndar nacional, la longitud de la estructura es la misma, pero hay un espacio entre la v\u00e1lvula de mariposa de clip, especialmente la diferencia de 6 y 8 pulgadas entre las dos especificaciones. \/est\u00e1ndar es el m\u00e1s grande. Esta tambi\u00e9n es una forma de juzgar a un fabricante si es profesional en la producci\u00f3n de v\u00e1lvulas de mariposa est\u00e1ndar estadounidenses.<\/p>\n\n\n\n
En API 609 Categor\u00eda B, se especifica la v\u00e1lvula de mariposa de 6 pulgadas a 150 LB, la longitud de la estructura es de solo 57 mm y muchos fabricantes, o 70 mm, es la misma que el cuerpo de v\u00e1lvula est\u00e1ndar nacional, se puede ver que muchas normas estadounidenses Los fabricantes de v\u00e1lvulas de mariposa utilizan directamente el molde de v\u00e1lvula est\u00e1ndar nacional. El cuerpo de la v\u00e1lvula se modific\u00f3 al tama\u00f1o de conexi\u00f3n est\u00e1ndar americano.<\/p>\n\n\n\n

Estos son populares en sistemas de baja presi\u00f3n (Clase 150 o menos), ciclos de vida relativamente m\u00e1s bajos, los revestimientos de caucho tambi\u00e9n son buenos para servicios de lodos abrasivos.<\/p>\n\n\n\n

La mayor\u00eda de los tipos desplazados hacen que el disco gire libremente desde el asiento despu\u00e9s de algunos grados de rotaci\u00f3n, lo que minimiza el desgaste del asiento y aumenta la vida \u00fatil de la v\u00e1lvula. El tipo offset puede tener asientos de caucho, pol\u00edmero (PTFE u otro), metal y grafito o incluso metal. Mucha variedad, lo que los hace adecuados para una variedad de temperaturas y presiones.<\/p>\n\n\n\n

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\r\n\r\n\r\nAPI 609 Category B Butterfly Valve<\/h3>\r\n\r\n\r\n\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","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":"\r\n\r\nGET CHINA BUTTERFLY VALVE WITH HANDLES PRICELIST INFORMATION<\/strong><\/a>\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nButterfly valves are quarter-turn valves ideal for on\/off operations as well as modulating flow.

API 609 Butterfly Valve Working Principle<\/h2>\r\n\r\n\r\n\r\n\r\nThe key component of a butterfly valve is the disc, a metal ring that is positioned at the centerline of the pipe and connected to an external actuator (manual level or actuator) via a rod.\r\n\r\n\r\n\r\n\r\n\r\nCompared to a ball valve, the disc of a butterfly valve is always in contact with the fluid conveyed by the pipeline and creates, therefore, a pressure drop.\r\n\r\n\r\n\r\n\r\n\r\nIn the closed position, the disc blocks the bore of the valve, and, in an open position, the disc allows the passage of the fluid.\r\n\r\n\r\n\r\n\r\n\r\nA quarter turn movement is needed to switch the valve from a fully open to a fully closed position (and such movement can be executed as quickly as for ball valves).\r\n\r\n\r\n\r\n\r\n

What is API 609 Standard?<\/h2>\r\n\r\n\r\n\r\n\r\nAPI 609 is the American design standard for butterfly valves, which is divided into Category A and B.\r\n\r\n\r\n\r\n\r\n

Types of API 609 Butterfly Valve<\/h2>\r\n\r\n\r\n\r\n
API 609 Category A Butterfly Valve<\/h3>\r\n\r\n\r\n\r\n\r\nThe Centric or concentric butterfly valve is the primary type of butterfly valve design. 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\r\n\r\n\r\n
API 609 Category B Butterfly Valve<\/h3>\r\n\r\n\r\n\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","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":"\r\n\r\nGET CHINA BUTTERFLY VALVE WITH HANDLES PRICELIST INFORMATION<\/strong><\/a>\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nButterfly valves are quarter-turn valves ideal for on\/off operations as well as modulating flow.
