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 borboleta com classifica\u00e7\u00e3o de press\u00e3o e temperatura que possuem uma sede deslocada e uma configura\u00e7\u00e3o de disco exc\u00eantrico ou conc\u00eantrico. Essas v\u00e1lvulas podem ter uma classifica\u00e7\u00e3o de sede inferior \u00e0 classifica\u00e7\u00e3o do corpo. Os tamanhos cobertos s\u00e3o NPS 3 a NPS 24 para as Classes 150, 300 e 600.<\/p>\n\n\n\n
A v\u00e1lvula borboleta Classe B do padr\u00e3o API 609 especifica o comprimento da estrutura da v\u00e1lvula borboleta padr\u00e3o americano, v\u00e1lvula borboleta flangeada e v\u00e1lvula borboleta lug. Em compara\u00e7\u00e3o com a v\u00e1lvula borboleta GB de padr\u00e3o nacional, a v\u00e1lvula borboleta de flange e o comprimento da estrutura da v\u00e1lvula borboleta de padr\u00e3o nacional \u00e9 o mesmo, mas h\u00e1 uma lacuna entre a v\u00e1lvula borboleta de clipe, especialmente a diferen\u00e7a de 6 e 8 polegadas entre as duas especifica\u00e7\u00f5es \/padr\u00e3o \u00e9 maior. Esta tamb\u00e9m \u00e9 uma forma de julgar um fabricante se ele \u00e9 profissional na produ\u00e7\u00e3o de v\u00e1lvulas borboleta de padr\u00e3o americano.<\/p>\n\n\n\n
Na API 609 Categoria B, a v\u00e1lvula borboleta de 6 polegadas a 150LB \u00e9 especificada, o comprimento da estrutura \u00e9 de apenas 57 mm, e muitos fabricantes, ou 70 mm, \u00e9 o mesmo com o corpo da v\u00e1lvula padr\u00e3o nacional, pode-se ver que muitos padr\u00f5es americanos fabricantes de v\u00e1lvulas borboleta diretamente para usar o molde de v\u00e1lvula padr\u00e3o nacional. O corpo da v\u00e1lvula foi modificado para o tamanho de conex\u00e3o padr\u00e3o americano.<\/p>\n\n\n\n

Tipo \u201cconc\u00eantrico\u201d. Tamb\u00e9m conhecidas como v\u00e1lvulas borboleta revestidas de borracha. Eles s\u00e3o populares em sistemas de baixa press\u00e3o (Classe 150 ou menos), com ciclo de vida relativamente mais baixo e os revestimentos de borracha tamb\u00e9m s\u00e3o bons para servi\u00e7os de pasta abrasiva.<\/p>\n\n\n\n

A maioria dos tipos offset faz com que o disco gire livremente a partir da sede ap\u00f3s alguns graus de rota\u00e7\u00e3o, o que minimiza o desgaste da sede e aumenta a vida \u00fatil da v\u00e1lvula. O tipo offset pode ter sedes de borracha, pol\u00edmero (PTFE ou outro), metal e grafite ou mesmo metal. Muita variedade o que os torna adequados para uma variedade de temperaturas e press\u00f5es.<\/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.
