Como funciona uma v\u00e1lvula de reten\u00e7\u00e3o?<\/h2>\r\n\r\n\r\n\r\n\r\nA v\u00e1lvula de reten\u00e7\u00e3o geralmente indica a dire\u00e7\u00e3o do fluxo no corpo da v\u00e1lvula, quando a press\u00e3o do meio importado \u00e9 maior que o peso do disco, o disco \u00e9 aberto pelo meio e a v\u00e1lvula tamb\u00e9m abre. Pelo contr\u00e1rio, quando a press\u00e3o m\u00e9dia importada \u00e9 inferior ao peso do disco, o disco tamb\u00e9m est\u00e1 fechado e a v\u00e1lvula tamb\u00e9m est\u00e1 no estado fechado. Quando combinada com uma v\u00e1lvula globo, a v\u00e1lvula de reten\u00e7\u00e3o pode desempenhar um papel no isolamento de seguran\u00e7a. A desvantagem \u00e9 a alta resist\u00eancia e a m\u00e1 veda\u00e7\u00e3o no fechamento.\r\n\r\n\r\n\r\n\r\n

We deliver reliable, durable products that meet rigorous safety, performance, and testing requirements. We offer a wide range of valve types, sizes, and materials to suit oil and gas, petrochemical, power generation, and other heavy-duty applications, backed by experienced technical support, strict quality control, and timely delivery to ensure optimal system performance and long-term operational integrity. What is a Check Valve? Check valve is a type of forced backflow sealing valve, which can close the valve without leakage by applying pressure from the back medium. The media flow direction of the check valve can be from the front. Check Valve Types According to the movement mode of the disc, the check valve can be divided into the lifting check valve and swing check valve. According to the connection mode, the check valve can be divided into a wafer check valve, flange check valve, and welded check valve. How does a Check Valve work? Check valve will usually indicate the direction of flow in the valve body, when the pressure of the imported medium is greater than the weight of the disc, the disc is pushed open by the medium, and the valve also opens. On the contrary, when the imported medium pressure is less than the weight of the disc, the disc is also closed, and the valve is also in the closed state. When combined with a globe valve, the check valve can play a role in safety isolation. The disadvantage is high resistance, and poor sealing when closing.

Choose ZECO as Your Professional Check Valve Manufacturer ZECO water & API 6D check valves are widely used in water & oil pipelines all over the world. In our case, they are used at the entrance of the hydropower station turbine, and they are installed at the water supply, oil pipe, line, and natural gas system. They are often used instead of cast and forged gate valves, carbon chvalvesalve, pressure seal check valves, and so on. Although the check valve can shut off the backflow medium, its flow resistance coefficient also has a very important effort on performance, because the return valve is different from the gate valve and butterfly valve so that the gate or disc is fully open without any flow resistance. The check valve needs the medium to flush the disc before flowing through the valve body. ZECO\u2018s check valve is its r & d team to travel around the world and well-known check valve manufacturers to communicate, under, and on this basis, own unique innovation and development. ZECO check valve has a very small resistance coefficient, automatic shut-down when backwater, and reliable performance, and why do we say that? As we have our own designed and developed valve testing system, we conduct performance and sealteststest for each newly developed and finished production valve to ensure that the check valve can be normally used under operating conditions and meet the final requirements of customers. The spring and disc of the feed check valve play an important role in the whole valve. Therefore, for each spring, we will use the fatigue testing machine and the elastic testing machine to ensure that the spring can maintain its normal state for a long time; For each disc, we will use precision equipment, such as numerical control equipment, and processing center. It is because of the previous process to the final inspection of the assurance that the check valve is safe.\" \/>\n<meta property=\"og:url\" content=\"https:\/\/zecovalve.com\/pt\/categoria-do-produto\/check-valve\" \/>\n<meta property=\"og:site_name\" content=\"ZECO Valve\" \/>\n<meta property=\"og:image\" content=\"https:\/\/zecovalve.com\/wp-content\/uploads\/2022\/06\/flange-check-valve.jpg\" \/>\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\/product-category\/check-valve#webpage\",\"url\":\"https:\/\/zecovalve.com\/product-category\/check-valve\",\"name\":\"Check Valve Manufacturer - Competitive Check Valve Price | ZECO Valve\",\"isPartOf\":{\"@id\":\"https:\/\/zecovalve.com\/#website\"},\"breadcrumb\":{\"@id\":\"https:\/\/zecovalve.com\/product-category\/check-valve#breadcrumb\"},\"inLanguage\":\"pt-PT\",\"potentialAction\":[{\"@type\":\"ReadAction\",\"target\":[\"https:\/\/zecovalve.com\/product-category\/check-valve\"]}]},{\"@type\":\"BreadcrumbList\",\"@id\":\"https:\/\/zecovalve.com\/product-category\/check-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\/product-category\/check-valve\",\"url\":\"https:\/\/zecovalve.com\/product-category\/check-valve\",\"name\":\"Check Valve\"}}]}]}<\/script>\n<!-- \/ Yoast SEO Premium plugin. -->","_links":{"self":[{"href":"https:\/\/zecovalve.com\/pt\/wp-json\/wp\/v2\/product_cat\/2455","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/zecovalve.com\/pt\/wp-json\/wp\/v2\/product_cat"}],"about":[{"href":"https:\/\/zecovalve.com\/pt\/wp-json\/wp\/v2\/taxonomies\/product_cat"}],"wp:post_type":[{"href":"https:\/\/zecovalve.com\/pt\/wp-json\/wp\/v2\/product?product_cat=2455"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
