A fun\u00e7\u00e3o de uma v\u00e1lvula borboleta wafer \u00e9 reter uma veda\u00e7\u00e3o para proteger contra diferencial de press\u00e3o bidirecional no fluxo de fluido. Em outras palavras, a vers\u00e3o wafer das v\u00e1lvulas borboleta foi projetada para manter uma veda\u00e7\u00e3o herm\u00e9tica, protegendo contra um diferencial de press\u00e3o bidirecional para evitar qualquer refluxo em sistemas fabricados para fluxo unidirecional. Isto \u00e9 conseguido usando uma veda\u00e7\u00e3o bem ajustada, como um anel de veda\u00e7\u00e3o, gaxeta ou usinada com precis\u00e3o, juntamente com uma face de v\u00e1lvula plana nas se\u00e7\u00f5es a jusante e a montante da v\u00e1lvula.<\/p>\n\n\n

Alguns tipos de Wafer possuem dois, enquanto outros possuem quatro.<\/p>\n\n\n\n Os parafusos do flange s\u00e3o inseridos atrav\u00e9s dos orif\u00edcios dos dois flanges do tubo e dos orif\u00edcios de centraliza\u00e7\u00e3o da v\u00e1lvula borboleta. Os flanges do tubo s\u00e3o puxados um em dire\u00e7\u00e3o ao outro apertando os parafusos do flange, e a v\u00e1lvula borboleta \u00e9 fixada entre os flanges e mantida no lugar.<\/p>\n\n\n\n No caso de uma v\u00e1lvula borboleta tipo Lug, existem as chamadas \u201corelhas\u201d em toda a circunfer\u00eancia do corpo nas quais as roscas s\u00e3o inseridas. Desta forma, a v\u00e1lvula borboleta pode ser apertada contra os dois flanges do tubo usando 2 parafusos separados (um de cada lado).<\/p>\n\n\n\n Como a v\u00e1lvula borboleta \u00e9 fixada em cada flange em ambos os lados com parafusos separados e mais curtos, a chance de relaxamento por meio da expans\u00e3o t\u00e9rmica \u00e9 menor do que com uma v\u00e1lvula tipo Wafer. Como resultado, a vers\u00e3o Lug \u00e9 mais adequada para aplica\u00e7\u00f5es com grandes diferen\u00e7as de temperatura.<\/p>\n\n\n\n A v\u00e1lvula tipo wafer geralmente tem dois ou quatro furos sem rosca para fixar e alinhar a v\u00e1lvula dentro de dois flanges correspondentes. O estilo lug possui furos roscados que permitem ao usu\u00e1rio retirar uma extremidade da linha sem afetar o lado oposto, pois ela \u00e9 presa firmemente contra um flange com parafusos que combinam com as sali\u00eancias roscadas da v\u00e1lvula. Isto torna mais f\u00e1cil limpar, inspecionar, reparar ou substituir outras se\u00e7\u00f5es da tubula\u00e7\u00e3o, pois n\u00e3o h\u00e1 necessidade de desligar todo o sistema.<\/p>\n\n\n\n\n O que \u00e9 uma v\u00e1lvula de borboleta do 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.
