Das Absperrventil der Klasse B des API 609-Standards gibt die Strukturl\u00e4nge des amerikanischen Standard-Absperrventils, des Flansch-Absperrventils und des \u00d6sen-Absperrventils an. Im Vergleich zum nationalen Standard GB-Absperrventil ist die Strukturl\u00e4nge des Flansch-Absperrventils und des nationalen Standard-Absperrventils gleich, aber es gibt eine L\u00fccke zwischen dem Clip-Absperrventil, insbesondere der Unterschied von 6 Zoll und 8 Zoll zwischen den beiden Spezifikationen\/Standards ist am gr\u00f6\u00dften. Dies ist auch eine M\u00f6glichkeit, einen Hersteller zu beurteilen, ob er professionell in der Herstellung amerikanischer Standard-Absperrventile ist.<\/p>\n\n\n\n
In der API 609 Kategorie B ist das 6-Zoll- bis 150LB-Absperrventil spezifiziert, die Strukturl\u00e4nge betr\u00e4gt nur 57 mm, und viele Hersteller oder 70 mm sind gleich dem nationalen Standardventilk\u00f6rper. Es ist ersichtlich, dass viele amerikanische Standard-Absperrventilhersteller direkt die nationale Standardventilform verwenden. Der Ventilk\u00f6rper wurde an die amerikanische Standardanschlussgr\u00f6\u00dfe angepasst.<\/p>\n\n\n\n

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\nAPI 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":3159,"name":"api 609 cat a","slug":"api-609-cat-a","term_group":0,"term_taxonomy_id":3159,"taxonomy":"post_tag","description":"","parent":0,"count":2,"filter":"raw"},{"term_id":3157,"name":"api 609 cat b","slug":"api-609-cat-b","term_group":0,"term_taxonomy_id":3157,"taxonomy":"post_tag","description":"","parent":0,"count":2,"filter":"raw"},{"term_id":2628,"name":"API 609 Category A","slug":"api-609-category-a","term_group":0,"term_taxonomy_id":2628,"taxonomy":"post_tag","description":"","parent":0,"count":3,"filter":"raw"},{"term_id":2627,"name":"API 609 Category B","slug":"api-609-category-b","term_group":0,"term_taxonomy_id":2627,"taxonomy":"post_tag","description":"","parent":0,"count":3,"filter":"raw"},{"term_id":2630,"name":"API Butterfly Valve","slug":"api-butterfly-valve","term_group":0,"term_taxonomy_id":2630,"taxonomy":"post_tag","description":"","parent":0,"count":1,"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.

Druck- und temperaturbewertete Absperrklappen mit versetztem Ventilsitz und entweder exzentrischer oder konzentrischer Scheibenkonfiguration. Diese Ventile haben m\u00f6glicherweise eine Sitzbelastbarkeit, die geringer ist als die Geh\u00e4usebelastbarkeit. Die abgedeckten Gr\u00f6\u00dfen sind NPS 3 bis NPS 24 f\u00fcr die Klassen 150, 300 und 600.<\/p>\n\n\n\n
Das Absperrventil der Klasse B des API 609-Standards gibt die Strukturl\u00e4nge des amerikanischen Standard-Absperrventils, des Flansch-Absperrventils und des \u00d6sen-Absperrventils an. Im Vergleich zum nationalen Standard GB-Absperrventil ist die Strukturl\u00e4nge des Flansch-Absperrventils und des nationalen Standard-Absperrventils gleich, aber es gibt eine L\u00fccke zwischen dem Clip-Absperrventil, insbesondere der Unterschied von 6 Zoll und 8 Zoll zwischen den beiden Spezifikationen\/Standards ist am gr\u00f6\u00dften. Dies ist auch eine M\u00f6glichkeit, einen Hersteller zu beurteilen, ob er professionell in der Herstellung amerikanischer Standard-Absperrventile ist.<\/p>\n\n\n\n
In der API 609 Kategorie B ist das 6-Zoll- bis 150LB-Absperrventil spezifiziert, die Strukturl\u00e4nge betr\u00e4gt nur 57 mm, und viele Hersteller oder 70 mm sind gleich dem nationalen Standardventilk\u00f6rper. Es ist ersichtlich, dass viele amerikanische Standard-Absperrventilhersteller direkt die nationale Standardventilform verwenden. Der Ventilk\u00f6rper wurde an die amerikanische Standardanschlussgr\u00f6\u00dfe angepasst.<\/p>\n\n\n\n

\u201eKonzentrischer\u201c Typ. Auch bekannt als Absperrklappen mit Gummiauskleidung. Diese sind in Niederdrucksystemen (Klasse 150 oder weniger) beliebt, haben eine relativ geringere Lebensdauer und Gummiauskleidungen eignen sich auch gut f\u00fcr abrasive Schl\u00e4mme.<\/p>\n\n\n\n
Kategorie B Absperrklappen <\/mark><\/strong><\/a><\/h3>\n\n\n\n \u201eOffset\u201c-Typ, d. h. die Welle ist von der Scheibe versetzt, sodass sie h\u00f6here Differenzdr\u00fccke aushalten kann. Bei den meisten Offset-Typen dreht sich die Scheibe nach einigen Grad Drehung frei vom Sitz, was den Sitzverschlei\u00df minimiert und die Lebensdauer des Ventilzyklus erh\u00f6ht. Der Offset-Typ kann Sitze aus Gummi, Polymer (PTFE oder andere), Metall und Graphit oder sogar Metall haben. Gro\u00dfe Vielfalt, wodurch diese f\u00fcr eine Vielzahl von Temperaturen und Dr\u00fccken geeignet sind.<\/p>\n\n\n\n

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\nAPI 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":3159,"name":"api 609 cat a","slug":"api-609-cat-a","term_group":0,"term_taxonomy_id":3159,"taxonomy":"post_tag","description":"","parent":0,"count":2,"filter":"raw"},{"term_id":3157,"name":"api 609 cat b","slug":"api-609-cat-b","term_group":0,"term_taxonomy_id":3157,"taxonomy":"post_tag","description":"","parent":0,"count":2,"filter":"raw"},{"term_id":2628,"name":"API 609 Category A","slug":"api-609-category-a","term_group":0,"term_taxonomy_id":2628,"taxonomy":"post_tag","description":"","parent":0,"count":3,"filter":"raw"},{"term_id":2627,"name":"API 609 Category B","slug":"api-609-category-b","term_group":0,"term_taxonomy_id":2627,"taxonomy":"post_tag","description":"","parent":0,"count":3,"filter":"raw"},{"term_id":2630,"name":"API Butterfly Valve","slug":"api-butterfly-valve","term_group":0,"term_taxonomy_id":2630,"taxonomy":"post_tag","description":"","parent":0,"count":1,"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.

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
API 609 Butterfly Valve Working Principle<\/h2>\r\n\r\n\r\n\r\n\r\nThe key component of a butterfly valve is the disc, a metal ring that is positioned at the centerline of the pipe and connected to an external actuator (manual level or actuator) via a rod.\r\n\r\n\r\n\r\n\r\n\r\nCompared to a ball valve, the disc of a butterfly valve is always in contact with the fluid conveyed by the pipeline and creates, therefore, a pressure drop.\r\n\r\n\r\n\r\n\r\n\r\nIn the closed position, the disc blocks the bore of the valve, and, in an open position, the disc allows the passage of the fluid.\r\n\r\n\r\n\r\n\r\n\r\nA quarter turn movement is needed to switch the valve from a fully open to a fully closed position (and such movement can be executed as quickly as for ball valves).\r\n\r\n\r\n\r\n\r\n

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

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":3159,"name":"api 609 cat a","slug":"api-609-cat-a","term_group":0,"term_taxonomy_id":3159,"taxonomy":"post_tag","description":"","parent":0,"count":2,"filter":"raw"},{"term_id":3157,"name":"api 609 cat b","slug":"api-609-cat-b","term_group":0,"term_taxonomy_id":3157,"taxonomy":"post_tag","description":"","parent":0,"count":2,"filter":"raw"},{"term_id":2628,"name":"API 609 Category A","slug":"api-609-category-a","term_group":0,"term_taxonomy_id":2628,"taxonomy":"post_tag","description":"","parent":0,"count":3,"filter":"raw"},{"term_id":2627,"name":"API 609 Category B","slug":"api-609-category-b","term_group":0,"term_taxonomy_id":2627,"taxonomy":"post_tag","description":"","parent":0,"count":3,"filter":"raw"},{"term_id":2630,"name":"API Butterfly Valve","slug":"api-butterfly-valve","term_group":0,"term_taxonomy_id":2630,"taxonomy":"post_tag","description":"","parent":0,"count":1,"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.
