O que \u00e9 uma v\u00e1lvula borboleta API 609?<\/h2>\r\n\r\n\r\n\r\n\r\nUma v\u00e1lvula borboleta \u00e9 usada para desligar ou modular o fluxo de um fluido (isolamento e regula\u00e7\u00e3o). As v\u00e1lvulas borboleta c\u00eantricas API 609 (sede macia) s\u00e3o preferidas \u00e0s v\u00e1lvulas gaveta e esfera para aplica\u00e7\u00f5es de baixa press\u00e3o e n\u00e3o cr\u00edticas, pois s\u00e3o mais baratas, mais leves e mais f\u00e1ceis de instalar. As v\u00e1lvulas borboleta exc\u00eantricas (v\u00e1lvulas de deslocamento duplo e triplo) com sedes met\u00e1licas cresceram em popularidade e competem com v\u00e1lvulas globo e esfera em algumas aplica\u00e7\u00f5es.\r\n\r\n\r\n\r\n\r\n\r\nOBTER PRE\u00c7O DA V\u00c1LVULA BORBOLETA API 609<\/strong><\/a>\r\n\r\n\r\n\r\n\r\n

Tipos de v\u00e1lvula borboleta API 609<\/h2>\r\n\r\n\r\n\r\n

V\u00e1lvula borboleta API 609 categoria A<\/h3>\r\n\r\n\r\n\r\n\r\nA v\u00e1lvula borboleta c\u00eantrica ou conc\u00eantrica \u00e9 o principal tipo de projeto de v\u00e1lvula borboleta. Neste projeto da v\u00e1lvula, a haste cruza a linha central do disco. Entre o furo do tubo e a sede, existe o limite do di\u00e2metro interno. Esta v\u00e1lvula de deslocamento zero tamb\u00e9m \u00e9 chamada de sede resiliente porque depende da adaptabilidade da borracha da sede para vedar o fluxo ap\u00f3s fech\u00e1-la com efici\u00eancia. Em torno de 85\u00b0 durante uma rota\u00e7\u00e3o de 90\u00b0, o disco entra primeiro em conex\u00e3o com a sede neste tipo de v\u00e1lvula. As v\u00e1lvulas borboleta conc\u00eantricas s\u00e3o geralmente usadas para aplica\u00e7\u00f5es de baixa press\u00e3o.\r\n\r\n\r\n\r\n\r\n

V\u00e1lvula borboleta API 609 categoria B<\/h3>\r\n\r\n\r\n\r\n\r\nNa v\u00e1lvula borboleta exc\u00eantrica, a haste passa atr\u00e1s da linha central do disco em vez de passar por ela. Como a haste est\u00e1 posicionada atr\u00e1s da linha central, a v\u00e1lvula \u00e9 chamada de deslocamento \u00fanico. Este design ajuda a minimizar o contato do disco com a veda\u00e7\u00e3o, o que aumenta a vida \u00fatil da v\u00e1lvula. Em v\u00e1lvulas borboleta de duplo deslocamento ou v\u00e1lvulas borboleta duplamente exc\u00eantricas, a haste \u00e9 posicionada na parte traseira do disco com um deslocamento extra. Este design de haste permite que o disco girat\u00f3rio cubra a sede apenas de um a tr\u00eas graus. Uma v\u00e1lvula borboleta de deslocamento triplo \u00e9 frequentemente usada em aplica\u00e7\u00f5es mais complexas que possuem o mesmo design de uma v\u00e1lvula borboleta de deslocamento duplo. Uma v\u00e1lvula borboleta de deslocamento triplo \u00e9 eficiente e reduz o desgaste. Esta v\u00e1lvula possui sedes de metal que criam um fechamento \u00e0 prova de bolhas e a tornam capaz de ser usada em aplica\u00e7\u00f5es de temperaturas mais altas.\r\n\r\n","link":"https:\/\/zecovalve.com\/pt\/tag\/api-609-butterfly-valve","name":"V\u00e1lvula borboleta API 609","slug":"api-609-butterfly-valve","taxonomy":"post_tag","meta":[],"yoast_head":"\nAPI 609 Butterfly Valve - Butterfly Valve Manufacturer | ZECO Valve<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/zecovalve.com\/pt\/tag\/api-609-butterfly-valve\" \/>\n<meta property=\"og:locale\" content=\"pt_PT\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"API 609 Butterfly Valve - Butterfly Valve Manufacturer | ZECO Valve\" \/>\n<meta property=\"og:description\" content=\"What is API 609 Standard? API 609 is the American design standard for butterfly valves, which is divided into Category A and B. What is an API 609 Butterfly Valve? A 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. GET API 609 BUTTERFLY VALVE PRICE Types of API 609 Butterfly Valve API 609 Category A Butterfly Valve The 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. API 609 Category B Butterfly Valve In 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.\" \/>\n<meta property=\"og:url\" content=\"https:\/\/zecovalve.com\/pt\/tag\/api-609-butterfly-valve\" \/>\n<meta property=\"og:site_name\" content=\"ZECO Valve\" \/>\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\/\/schema.org\",\"@graph\":[{\"@type\":\"WebSite\",\"@id\":\"https:\/\/zecovalve.com\/#website\",\"url\":\"https:\/\/zecovalve.com\/\",\"name\":\"ZECO Valve\",\"description\":\"Industrial Ball Valve, Gate Valve and Globe Valve Manufacturer\",\"potentialAction\":[{\"@type\":\"SearchAction\",\"target\":\"https:\/\/zecovalve.com\/?s={search_term_string}\",\"query-input\":\"required name=search_term_string\"}],\"inLanguage\":\"pt-PT\"},{\"@type\":\"CollectionPage\",\"@id\":\"https:\/\/zecovalve.com\/tag\/api-609-butterfly-valve#webpage\",\"url\":\"https:\/\/zecovalve.com\/tag\/api-609-butterfly-valve\",\"name\":\"API 609 Butterfly Valve - Butterfly Valve Manufacturer | ZECO Valve\",\"isPartOf\":{\"@id\":\"https:\/\/zecovalve.com\/#website\"},\"breadcrumb\":{\"@id\":\"https:\/\/zecovalve.com\/tag\/api-609-butterfly-valve#breadcrumb\"},\"inLanguage\":\"pt-PT\",\"potentialAction\":[{\"@type\":\"ReadAction\",\"target\":[\"https:\/\/zecovalve.com\/tag\/api-609-butterfly-valve\"]}]},{\"@type\":\"BreadcrumbList\",\"@id\":\"https:\/\/zecovalve.com\/tag\/api-609-butterfly-valve#breadcrumb\",\"itemListElement\":[{\"@type\":\"ListItem\",\"position\":1,\"item\":{\"@type\":\"WebPage\",\"@id\":\"https:\/\/zecovalve.com\/\",\"url\":\"https:\/\/zecovalve.com\/\",\"name\":\"Home\"}},{\"@type\":\"ListItem\",\"position\":2,\"item\":{\"@type\":\"WebPage\",\"@id\":\"https:\/\/zecovalve.com\/tag\/api-609-butterfly-valve\",\"url\":\"https:\/\/zecovalve.com\/tag\/api-609-butterfly-valve\",\"name\":\"API 609 Butterfly Valve\"}}]}]}<\/script>\n<!-- \/ Yoast SEO Premium plugin. -->","_links":{"self":[{"href":"https:\/\/zecovalve.com\/pt\/wp-json\/wp\/v2\/tags\/2629","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/zecovalve.com\/pt\/wp-json\/wp\/v2\/tags"}],"about":[{"href":"https:\/\/zecovalve.com\/pt\/wp-json\/wp\/v2\/taxonomies\/post_tag"}],"wp:post_type":[{"href":"https:\/\/zecovalve.com\/pt\/wp-json\/wp\/v2\/posts?tags=2629"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
