O que \u00e9 uma v\u00e1lvula borboleta?<\/h2>\r\n\r\n\r\n\r\n\r\nA v\u00e1lvula borboleta \u00e9 uma v\u00e1lvula que pode ser usada para isolar ou regular o fluxo. O mecanismo de fechamento tem a forma de um disco. O funcionamento \u00e9 semelhante ao das V\u00e1lvulas Esfera, o que permite um desligamento r\u00e1pido. As v\u00e1lvulas borboleta s\u00e3o geralmente preferidas porque t\u00eam custo mais baixo do que outros designs de v\u00e1lvula, al\u00e9m de serem mais leves, o que significa que \u00e9 necess\u00e1rio menos suporte. O disco \u00e9 posicionado no centro do tubo, passando pelo disco h\u00e1 uma haste conectada a um atuador na parte externa da v\u00e1lvula. Girar o atuador gira o disco paralelo ou perpendicular ao fluxo. Ao contr\u00e1rio de uma v\u00e1lvula esfera, o disco est\u00e1 sempre presente no fluxo, portanto uma queda de press\u00e3o \u00e9 sempre induzida no fluxo, independentemente da posi\u00e7\u00e3o da v\u00e1lvula.\r\n\r\n\r\n\r\n\r\n\r\nOBTER PRE\u00c7O DA V\u00c1LVULA BORBOLETA<\/strong><\/a>\r\n\r\n\r\n\r\n\r\n

    • O projeto mais b\u00e1sico de uma v\u00e1lvula borboleta \u00e9 uma v\u00e1lvula borboleta c\u00eantrica ou conc\u00eantrica. A haste passa pela linha central do disco e a sede fica na periferia do di\u00e2metro interno do corpo da v\u00e1lvula (Figura 4 \u00e0 esquerda). Este projeto de v\u00e1lvula de deslocamento zero \u00e9 conhecido como sede resiliente porque a veda\u00e7\u00e3o eficiente depende da flexibilidade da sede de borracha. Ao fechar, o disco entra primeiro em contato com a sede em cerca de 85\u00b0 durante uma rota\u00e7\u00e3o de 90\u00b0. As v\u00e1lvulas borboleta conc\u00eantricas s\u00e3o adequadas para faixas de baixa press\u00e3o.<\/li>\r\n<\/ul>\r\n<\/li>\r\n \t

        • As v\u00e1lvulas borboleta de triplo deslocamento s\u00e3o essenciais em aplica\u00e7\u00f5es onde \u00e9 necess\u00e1ria uma veda\u00e7\u00e3o estanque a bolhas.

Butterfly Valve is a valve that can be used for isolating or regulating flow. The closing mechanism takes the form of a disk. Operation is similar to that of Ball Valves, which allows for quick shut-off. Butterfly valves are generally favored because they are lower in cost than other valve designs as well as being lighter in weight, meaning less support is required. The disc is positioned in the center of the pipe, passing through the disc is a rod connected to an actuator on the outside of the valve. Rotating the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball valve, the disc is always present within the flow, therefore a pressure drop is always induced in the flow, regardless of valve position. GET BUTTERFLY VALVE PRICE Types of Butterfly Valves Concentric Butterfly Valve The most basic design of a butterfly valve is a centric or concentric butterfly valve. The stem passes through the disc\u2019s centerline, and the seat is the inside diameter periphery of the valve body (Figure 4 on the left). This zero-offset valve design is known as resilient-seated because efficient sealing relies on the flexibility of the rubber seat. When closing, the disc first comes into contact with the seat at around 85\u00b0 during a 90\u00b0 rotation. Concentric butterfly valves are suitable for low-pressure ranges. Double Offset Butterfly Valve This popular valve is also known as a high-performance butterfly valve. This valve has two stems offset from the center. This creates a cam action during the application’s process. Triple Offset Butterfly Valve Triple Offset Butterfly Valves are essential in applications where a bubble-tight shut-off is required. In some applications, bubble-tight shut-off cannot be achieved using double offset butterfly valves. Some applications do not lend themselves well to traditional butterfly valves, for example, applications involving harsh chemicals or media with small particles prone to clogging valves and pipelines. Gate Valve vs Butterfly Valve Butterfly valves are comparatively more extensively used in large sizes compared to gate valves. Because butterfly valves open and close quickly and can be frequently operated, they are ideal for applications that require quick opening and closing, especially for emergency shutoffs.\" \/>\n<meta property=\"og:url\" content=\"https:\/\/zecovalve.com\/pt\/tag\/butterfly-valve-wikipedia\" \/>\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\/butterfly-valve-wikipedia#webpage\",\"url\":\"https:\/\/zecovalve.com\/tag\/butterfly-valve-wikipedia\",\"name\":\"Butterfly Valve Wikipedia - Type of Butterfly Valve | ZECO Valve\",\"isPartOf\":{\"@id\":\"https:\/\/zecovalve.com\/#website\"},\"breadcrumb\":{\"@id\":\"https:\/\/zecovalve.com\/tag\/butterfly-valve-wikipedia#breadcrumb\"},\"inLanguage\":\"pt-PT\",\"potentialAction\":[{\"@type\":\"ReadAction\",\"target\":[\"https:\/\/zecovalve.com\/tag\/butterfly-valve-wikipedia\"]}]},{\"@type\":\"BreadcrumbList\",\"@id\":\"https:\/\/zecovalve.com\/tag\/butterfly-valve-wikipedia#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\/butterfly-valve-wikipedia\",\"url\":\"https:\/\/zecovalve.com\/tag\/butterfly-valve-wikipedia\",\"name\":\"Butterfly Valve Wikipedia\"}}]}]}<\/script>\n<!-- \/ Yoast SEO Premium plugin. -->","_links":{"self":[{"href":"https:\/\/zecovalve.com\/pt\/wp-json\/wp\/v2\/tags\/1881","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=1881"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
