{"id":3235,"count":5,"description":"\r\n\r\nEl asiento de v\u00e1lvula o anillo de asiento se utiliza para soportar el obturador o disco de la v\u00e1lvula en una posici\u00f3n completamente cerrada y para formar una pieza de sellado. Normalmente, el di\u00e1metro del asiento de la v\u00e1lvula es el di\u00e1metro de flujo m\u00e1ximo de la v\u00e1lvula. El material del asiento es muy amplio, se pueden utilizar todo tipo de materiales de caucho, pl\u00e1stico y metal como material del asiento, como EPDM, NBR, NR, PTF.E, PEEK, PFA, SS315, STELLITE, etc.\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nOBTENER PRECIO DE ANILLOS DE ASIENTO DE V\u00c1LVULA<\/strong><\/a>\r\n\r\n\r\n\r\n\r\n\r\nPara la v\u00e1lvula de mariposa, el material del asiento suele ser caucho, como EPDM, NBR, NR (caucho duro natural).\r\n\r\n\r\n\r\n\r\n\r\nPara la v\u00e1lvula de bola y la v\u00e1lvula de tap\u00f3n, el material del asiento suele ser pl\u00e1stico, como PTFE, PEEK, etc.\r\n\r\n\r\n\r\n\r\n\r\nPara la v\u00e1lvula de globo y la v\u00e1lvula de compuerta, el material del asiento suele ser metal con metal.\r\n\r\n\r\n\r\n\r\n\r\nPara las v\u00e1lvulas que utilizan material de asiento blando, su rendimiento de cierre es excelente e incluso pueden alcanzar una estanqueidad del asiento de cero burbujas. mientras que la desventaja es que no pueden resistir aplicaciones de alta temperatura y alta presi\u00f3n.\r\n\r\n\r\n\r\n\r\n\r\nOn the other hand, those valve's seat material is metal to metal therefore they can stand with high-pressure ratings up to 2500LB.\r\n\r\n\r\n\r\n\r\n

Tipos de anillos de asiento<\/h2>\r\n\r\n\r\n\r\n

Asiento blando (anillo de asiento no met\u00e1lico)<\/h3>\r\n\r\n\r\n\r\n\r\nLa mayor\u00eda de las v\u00e1lvulas tienen inserciones de asiento blando y sellos de elast\u00f3mero o pol\u00edmero. El anillo de asiento no met\u00e1lico est\u00e1 fabricado, por ejemplo, de tefl\u00f3n. El anillo se sujeta contra la bola mediante un inserto. Para un servicio a prueba de incendios, se requiere una disposici\u00f3n secundaria de asiento de metal con metal para evitar fugas en caso de que el material blando del asiento se pierda durante un incendio. Las v\u00e1lvulas de asiento blando se recomiendan \u00fanicamente para servicio limpio y no son adecuadas para servicio sucio\/abrasivo o altas temperaturas.\r\n\r\n\r\n\r\n\r\n

Anillo de sellado doble biselado<\/h3>\r\n\r\n\r\n\r\n\r\nSe ha adoptado el dise\u00f1o de la estructura de un anillo de sellado de doble bisel para reducir la fricci\u00f3n entre la bola y el anillo de sellado y lograr un par de funcionamiento m\u00e1s bajo. Cuando la presi\u00f3n media es baja, la bola tiene una superficie de contacto m\u00e1s peque\u00f1a con un anillo de sellado, lo que introduce una presi\u00f3n de sellado m\u00e1s alta para garantizar la confiabilidad del sellado. Cuando la presi\u00f3n media aumenta, el \u00e1rea de contacto entre la bola y el anillo de sellado aumenta en consecuencia. Un \u00e1rea de contacto m\u00e1s grande reduce la presi\u00f3n de sellado para evitar la deformaci\u00f3n del anillo de sellado.\r\n\r\n\r\n\r\n\r\n

Anillos de asiento con labios en voladizo<\/h3>\r\n\r\n\r\n\r\n\r\nLos anillos de asiento con labios en voladizo est\u00e1n dise\u00f1ados de manera que la bola haga contacto inicialmente s\u00f3lo con la punta del labio. A medida que los asientos aguas arriba y aguas abajo est\u00e1n pretensados en un conjunto contra la bola, los labios se desv\u00edan y torsionan los anillos del asiento. Cuando la v\u00e1lvula se cierra contra la presi\u00f3n de la l\u00ednea, el labio del asiento aguas abajo se desv\u00eda a\u00fan m\u00e1s hasta que finalmente toda la superficie del asiento coincide con la bola. Gracias a este dise\u00f1o, los asientos tienen cierta acci\u00f3n de resorte que promueve una buena acci\u00f3n de sellado tambi\u00e9n a bajas presiones de fluido. Adem\u00e1s, la construcci\u00f3n resistente evita que los asientos se aplasten con cargas elevadas de fluido.\r\n\r\n\r\n\r\n\r\n

Ranuras de compensaci\u00f3n de presi\u00f3n<\/h3>\r\n\r\n\r\n\r\n\r\nEl anillo de asiento representado est\u00e1 provisto de ranuras perif\u00e9ricas, denominadas ranuras de compensaci\u00f3n de presi\u00f3n. Durante el cierre de la v\u00e1lvula, se produce la sobrepresi\u00f3n m\u00e1xima, durante la cual el asiento aguas abajo puede verse obligado a entrar en el puerto de bola y la v\u00e1lvula puede quedar inoperativa. Las ranuras de compensaci\u00f3n de presi\u00f3n evitan esta posible falla. Cuando la presi\u00f3n hace que el asiento aguas arriba se mueva contra la bola y la bola se mueve aguas abajo, la presi\u00f3n simplemente se filtra hacia la cavidad del cuerpo de la v\u00e1lvula a trav\u00e9s de las ranuras de alivio. El anillo de asiento aguas arriba se equilibra en presi\u00f3n. El sellado aguas abajo evita da\u00f1os en el asiento y reduce el par de operaci\u00f3n al tiempo que proporciona capacidad bidireccional total. Los asientos con ranuras de compensaci\u00f3n de presi\u00f3n tambi\u00e9n permiten que la v\u00e1lvula funcione a un diferencial de presi\u00f3n m\u00e1s alto con pares de torsi\u00f3n m\u00e1s bajos que las v\u00e1lvulas de doble sellado en las que hay sellado entre ambos asientos y la bola.\r\n\r\n\r\n\r\n\r\n

Asiento blando (anillo de asiento met\u00e1lico)<\/h3>\r\n\r\n\r\n\r\n\r\nEl anillo de asiento met\u00e1lico, que contiene un inserto no met\u00e1lico, generalmente requiere fuerza de resorte para lograr un sello herm\u00e9tico. Debido a los resortes, este dise\u00f1o no se utiliza en servicios corrosivos. Aunque este asiento tiene un anillo de asiento de metal, se clasifica como una v\u00e1lvula de bola de asiento blando debido al uso de un inserto de material blando, que est\u00e1 en contacto con la bola.\r\n\r\n\r\n\r\n\r\n

Asientos de metal con metal<\/h3>\r\n\r\n\r\n\r\n\r\nPara servicios no aptos para asientos blandos, se utilizan asientos de metal y cer\u00e1mica. En la pr\u00e1ctica general, las v\u00e1lvulas de bola con asiento de metal duro (t\u00edpicamente estelita) s\u00f3lo se utilizan en condiciones de servicio severas como alta temperatura, alta erosi\u00f3n, corrosi\u00f3n o abrasi\u00f3n, lodo, etc. Los asientos de metal generalmente no son herm\u00e9ticos. Los asientos y bolas de metal generalmente se lapean en juegos coincidentes, lo que da como resultado una redondez y aptitud perfectas para garantizar un funcionamiento suave y un cierre herm\u00e9tico y lograr una "fuga cero". Los asientos de metal vienen en diferentes clases de cierre, incluidas Clase IV, V y VI. El asiento y la bola de metal est\u00e1n fabricados con metales base recubiertos con cromo duro, carburo de tungsteno y estelita.\r\n\r\n","link":"https:\/\/zecovalve.com\/es\/tag\/valve-seat-rings","name":"Anillos de asiento de v\u00e1lvula","slug":"valve-seat-rings","taxonomy":"post_tag","meta":[],"yoast_head":"\nValve Seat Rings - Seat Ring Valve - Butterfly Valve Seat Ring | ZECO<\/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\/es\/tag\/valve-seat-rings\" \/>\n<meta property=\"og:locale\" content=\"es_ES\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Valve Seat Rings - Seat Ring Valve - Butterfly Valve Seat Ring | ZECO\" \/>\n<meta property=\"og:description\" content=\"The Valve seat or seat ring is used to support the valve plug or disc in a fully closed position and to form a sealing part. Usually, the valve seat diameter is the maximum flow diameter of the valve. The seat material is very wide, all kinds of rubber, plastic, and metal materials can be used as seat material, such as EPDM, NBR, NR, PTF.E, PEEK, PFA, SS315, STELLITE, and so on GET VALVE SEAT RINGS PRICE For the butterfly valve, the seat material usually are rubbers, such as EPDM, NBR, NR (Natural hard rubber) For the ball valve and plug valve the seat material usually is plastics, such as PTFE, PEEK, and so on. For the globe valve and gate valve the seat material usually is metal to metal. For valves using soft seat material, their shut-off performance is great and even can reach zero bubble seat tightness. while the disadvantaged part is they can not resist high temperature and high-pressure applications. On the other hand, those valve’s seat material is metal to metal therefore they can stand with high-pressure ratings up to 2500LB. Types of Seat Rings Soft Seat (Nonmetallic Seat Ring) The majority of valves have soft seat inserts and elastomer or polymer seals. The nonmetallic seat ring is made from e.g. Teflon. The ring is held against the ball by an insert. For fire-safe service, a secondary metal-to-metal seating arrangement is required to omit leakage in the event that the soft seat material is lost during a fire. Soft seated valves are recommended for clean service only and are unsuitable for dirty\/abrasive service or high temperatures. Double Beveled Sealing Ring The structure design of a double-beveled sealing ring has been adopted to reduce the friction between the ball and the sealing ring to achieve lower operating torque. When the medium pressure is low, the ball has a smaller contacting surface with a sealing ring, which introduces higher sealing pressure to ensure the sealing reliability. When the medium pressure gets higher, the contacting area between the ball and the sealing ring increases accordingly. A larger contact area reduces the sealing pressure to avoid the deformation of the sealing ring. Cantilevered lips seat rings Seat rings with cantilevered lips are designed so that the ball contacts initially only the tip of the lip. As the upstream and downstream seats are pre-stressed on an assembly against the ball, the lips de\ufb02ect and put the seat rings into a torsion. When the valve is being closed against the line pressure, the lip of the downstream seat de\ufb02ects still further until \ufb01nally the entire seat surface matches the ball. By this design, the seats have some spring action that promotes good sealing action also at low \ufb02uid pressures. Furthermore, the resilient construction keeps the seats from being crushed at high \ufb02uid loads Pressure equalizing slots The seat ring shown is provided with peripheral slots, which are known as pressure-equalizing slots. During the closing of the valve, the maximum surge pressure occurs, during which the downstream seat can be forced to intrude into the ball port and the valve can become inoperative. The pressure equalizing slots prevents this potential failure. When pressure causes the upstream seat to move against the ball and the ball moves downstream, the pressure simply leaks into the valve body cavity through the relief slots. The upstream seat ring becomes pressure balanced. Downstream sealing prevents seat damage and lowers operating torque while providing full bidirectional capability. The seats with pressure equalizing slots also permit the valve to operate at a higher pressure differential with lower torques than double sealing valves in which there is sealing between both seats and the ball. Soft Seat (Metallic Seat Ring) The metallic seat ring, containing a nonmetallic insert, usually requires spring force to achieve a tight seal. Due to springs, this design is not used in corrosive service. Even though this seat has a metal seat ring, it is categorized as a soft seated ball valve due to its use of soft material insert, which is in contact with the ball. Metal to Metal Seats For services unsuitable for soft seating, metal and ceramic seating are being used. In general practice, hard metal seated ball valves (typically stellite) are only used in severe service conditions such as high temperature, high erosion, corrosion or abrasion, slurry, etc. Metal seats are generally not bubble tight. Metal seats and balls are typically lapped in matching sets resulting in perfect roundness and fitness to ensure smooth operation and tight shut-off and achieving \u2018Zero Leakage\u2019. Metal seats come in different classes of Shut Off including Class IV, V, and VI. Metal Seat and Ball are fabricated from base metals coated with hard chrome, tungsten carbide, and Stellite.\" \/>\n<meta property=\"og:url\" content=\"https:\/\/zecovalve.com\/es\/tag\/valve-seat-rings\" \/>\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\":\"es\"},{\"@type\":\"CollectionPage\",\"@id\":\"https:\/\/zecovalve.com\/tag\/valve-seat-rings#webpage\",\"url\":\"https:\/\/zecovalve.com\/tag\/valve-seat-rings\",\"name\":\"Valve Seat Rings - Seat Ring Valve - Butterfly Valve Seat Ring | ZECO\",\"isPartOf\":{\"@id\":\"https:\/\/zecovalve.com\/#website\"},\"breadcrumb\":{\"@id\":\"https:\/\/zecovalve.com\/tag\/valve-seat-rings#breadcrumb\"},\"inLanguage\":\"es\",\"potentialAction\":[{\"@type\":\"ReadAction\",\"target\":[\"https:\/\/zecovalve.com\/tag\/valve-seat-rings\"]}]},{\"@type\":\"BreadcrumbList\",\"@id\":\"https:\/\/zecovalve.com\/tag\/valve-seat-rings#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\/valve-seat-rings\",\"url\":\"https:\/\/zecovalve.com\/tag\/valve-seat-rings\",\"name\":\"Valve Seat Rings\"}}]}]}<\/script>\n<!-- \/ Yoast SEO Premium plugin. -->","_links":{"self":[{"href":"https:\/\/zecovalve.com\/es\/wp-json\/wp\/v2\/tags\/3235","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/zecovalve.com\/es\/wp-json\/wp\/v2\/tags"}],"about":[{"href":"https:\/\/zecovalve.com\/es\/wp-json\/wp\/v2\/taxonomies\/post_tag"}],"wp:post_type":[{"href":"https:\/\/zecovalve.com\/es\/wp-json\/wp\/v2\/posts?tags=3235"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
