La funci\u00f3n de una v\u00e1lvula de mariposa tipo wafer es retener un sello para proteger contra la diferencia de presi\u00f3n bidireccional en el flujo de fluido. En otras palabras, la versi\u00f3n tipo oblea de las v\u00e1lvulas de mariposa fue dise\u00f1ada para mantener un sello herm\u00e9tico, protegiendo contra un diferencial de presi\u00f3n bidireccional para evitar cualquier contraflujo en sistemas fabricados para flujo unidireccional. Esto se logra mediante el uso de un sello bien ajustado, como una junta t\u00f3rica, una junta o mecanizado con precisi\u00f3n, junto con una cara plana de la v\u00e1lvula en las secciones aguas abajo y aguas arriba de la v\u00e1lvula.<\/p>\n\n\n

Algunos tipos de Wafer tienen dos, mientras que otros tienen cuatro.<\/p>\n\n\n\n Los pernos de la brida se insertan a trav\u00e9s de los orificios para pernos de las dos bridas de la tuber\u00eda y los orificios de centrado de la v\u00e1lvula de mariposa. Las bridas de la tuber\u00eda se acercan entre s\u00ed apretando los pernos de la brida y la v\u00e1lvula de mariposa se sujeta entre las bridas y se mantiene en su lugar.<\/p>\n\n\n\n En el caso de una v\u00e1lvula de mariposa tipo Lug, a lo largo de toda la circunferencia del cuerpo se encuentran las llamadas "orejas", en las que se introducen los hilos. De esta manera, la v\u00e1lvula de mariposa se puede apretar contra las dos bridas de la tuber\u00eda usando 2 pernos separados (uno a cada lado).<\/p>\n\n\n\n Debido a que la v\u00e1lvula de mariposa est\u00e1 unida a cada brida en ambos lados con pernos m\u00e1s cortos y separados, la posibilidad de relajaci\u00f3n debido a la expansi\u00f3n t\u00e9rmica es menor que con una v\u00e1lvula estilo Wafer. Como resultado, la versi\u00f3n Lug es m\u00e1s adecuada para aplicaciones con grandes diferencias de temperatura.<\/p>\n\n\n\n La v\u00e1lvula estilo wafer generalmente tiene dos o cuatro orificios sin rosca para asegurar y alinear la v\u00e1lvula dentro de dos bridas coincidentes. El estilo de orejeta tiene orificios roscados que permiten al usuario quitar un extremo de la l\u00ednea sin afectar el lado opuesto, ya que se sujeta de forma segura contra una brida con pernos que coinciden con las orejetas roscadas de la v\u00e1lvula. Esto facilita la limpieza, inspecci\u00f3n, reparaci\u00f3n o reemplazo de otras secciones de tuber\u00edas, ya que no es necesario apagar todo el sistema.<\/p>\n\n\n\n\n \u00bfQu\u00e9 es una v\u00e1lvula de mariposa tipo lug?

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
What is an API 609 Butterfly Valve?<\/h2>\r\n\r\n\r\n\r\n\r\nA butterfly valve is used to shut off or modulate the flow of a fluid (isolation and regulation). API 609 Centric butterfly valves (soft seated) are preferred to gate and ball valves for low-pressure and non-critical applications as they are cheaper, lighter, and easier to install. Eccentric butterfly valves (double offset and triple offset valves) with metal seats have surged in popularity and compete with globe and ball valves for some applications.\r\n\r\n\r\n\r\n\r\n\r\nGET API 609 BUTTERFLY VALVE PRICE<\/strong><\/a>\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":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.
