<\/figure>\n<\/div>\n\n\nQual \u00e9 a diferen\u00e7a entre v\u00e1lvulas esfera de passagem total e v\u00e1lvulas esfera de passagem reduzida?<\/h2>\n\n\n\n- 1. Defini\u00e7\u00e3o:
- 1). A v\u00e1lvula esfera de passagem total \u00e9 um canal de fluxo de largura igual, ou seja, o tamanho do canal de fluxo da entrada \u00e0 sa\u00edda \u00e9 o mesmo, e seu tamanho n\u00e3o pode ser menor que o valor especificado na norma, que \u00e9 aproximadamente equivalente ao di\u00e2metro nominal da especifica\u00e7\u00e3o. Por exemplo, o di\u00e2metro do canal de fluxo da v\u00e1lvula esfera de passagem total DN50 deve ser de cerca de 50;<\/li>
- 2). A entrada do caminho de fluxo da v\u00e1lvula esf\u00e9rica redutora \u00e9 mais larga do que o di\u00e2metro do caminho de fluxo, e o di\u00e2metro real do caminho de fluxo \u00e9 cerca de uma especifica\u00e7\u00e3o menor que esta especifica\u00e7\u00e3o. Por exemplo, o caminho de fluxo da v\u00e1lvula esf\u00e9rica redutora DN50 \u00e9 de cerca de 38, que \u00e9 quase o mesmo que o da Dn40. Reduza uma especifica\u00e7\u00e3o dentro de DN250 e duas especifica\u00e7\u00f5es dentro de 250-600, e os 600 acima ser\u00e3o determinados de acordo com a situa\u00e7\u00e3o real.<\/li><\/ul><\/li>
- 2\u3001 M\u00eddia aplic\u00e1vel:
- 1). A v\u00e1lvula de esfera de passagem total \u00e9 geralmente usada para transportar tubula\u00e7\u00f5es m\u00e9dias viscosas e propensas a esc\u00f3ria. Devido \u00e0 sua pequena resist\u00eancia ao fluido, pode-se dizer que basicamente n\u00e3o h\u00e1 resist\u00eancia ao fluxo e \u00e9 conveniente para a passagem do raspador e soprador de parafina normal.<\/li>
- 2). A v\u00e1lvula esf\u00e9rica redutora \u00e9 adequada para transportar g\u00e1s ou meio com propriedades f\u00edsicas semelhantes \u00e0s da \u00e1gua, porque seu peso \u00e9 cerca de 30% mais leve que a v\u00e1lvula esf\u00e9rica de di\u00e2metro total e sua resist\u00eancia ao fluxo \u00e9 de apenas cerca de 1\/7 da v\u00e1lvula globo do mesmo di\u00e2metro. \u00c9 ben\u00e9fico reduzir a carga e o custo do gasoduto.<\/li><\/ul><\/li>
- 3. Processo aplic\u00e1vel:
- 1). Para o gasoduto que exige regular pigmenta\u00e7\u00e3o<\/a>, a v\u00e1lvula de esfera de passagem total deve ser usada independentemente do meio transportado. Quando o meio passa pela v\u00e1lvula esf\u00e9rica de passagem total, ele n\u00e3o reduzir\u00e1 o fluxo e a resist\u00eancia ao fluxo \u00e9 pequena, o que \u00e9 um produto ideal para controle de tubula\u00e7\u00f5es, especialmente para condi\u00e7\u00f5es de trabalho rigorosas. Em particular, quando os oleodutos principais em oleodutos e gasodutos precisam ser enterrados no subsolo, devem ser usadas v\u00e1lvulas de esfera soldadas de passagem total.<\/li>
- 2). A v\u00e1lvula de esfera redutora \u00e9 adequada para algumas condi\u00e7\u00f5es de trabalho com baixos requisitos e pequenos requisitos de resist\u00eancia \u00e0 convec\u00e7\u00e3o. Quando o di\u00e2metro interno da v\u00e1lvula \u00e9 superior a 80% do di\u00e2metro interno da extremidade do tubo, h\u00e1 pouco efeito na capacidade de fluxo do tubo. Muitas v\u00e1lvulas t\u00eam di\u00e2metro redutor, que geralmente \u00e9 controlado dentro de 0,8. Por um lado, a redu\u00e7\u00e3o do di\u00e2metro reduz a capacidade de vaz\u00e3o da v\u00e1lvula, ou seja, o valor Kv da v\u00e1lvula, aumenta a queda de press\u00e3o em ambas as extremidades da v\u00e1lvula, resultando em perda de energia. Para o gasoduto, n\u00e3o tem grande impacto, ou aumenta a descarga do gasoduto.<\/li><\/ul><\/li>
- 4. Compara\u00e7\u00e3o de vantagens e desvantagens:
- 1). Espa\u00e7o de instala\u00e7\u00e3o: o volume da v\u00e1lvula esfera redutora \u00e9 pequeno, portanto a necessidade de seu espa\u00e7o de instala\u00e7\u00e3o \u00e9 menor. Como seu peso \u00e9 cerca de 30% mais leve que a v\u00e1lvula de esfera de passagem total, \u00e9 ben\u00e9fico reduzir a carga da tubula\u00e7\u00e3o, a carga de transporte e o custo.<\/li>
- 2). Custo: o pre\u00e7o da v\u00e1lvula esf\u00e9rica redutora \u00e9 um grau inferior ao da v\u00e1lvula esf\u00e9rica de passagem total. Considerando o desempenho de custo, geralmente \u00e9 padronizado internacionalmente, e o corpo da v\u00e1lvula com o mesmo di\u00e2metro de esfera \u00e9 adotado para o di\u00e2metro do tubo adjacente. Por exemplo, DN32 e DN40, DN50 e DN63, DN90 e DN110, DN160 e DN200, DN250 e DN315 usam a mesma esfera.<\/li><\/ul><\/li><\/ul>\n\n\n\n
Como escolher?<\/h2>\n\n\n\n
Compreender a situa\u00e7\u00e3o do seu projeto, como tipo de meio, press\u00e3o e assim por diante.<\/p>\n\n\n\n
Se a press\u00e3o \u00e9 um fator que o preocupa muito, ent\u00e3o voc\u00ea precisa saber que a v\u00e1lvula esfera de di\u00e2metro reduzido causar\u00e1 quedas de press\u00e3o. E a v\u00e1lvula esf\u00e9rica de passagem total n\u00e3o.<\/p>\n\n\n\n
Se a sua tubula\u00e7\u00e3o precisar ser limpa regularmente, a v\u00e1lvula esfera de passagem total ser\u00e1 sua melhor escolha.<\/p>\n\n\n\n

This misunderstanding can lead you to buy the wrong valves for your project. Among the many types of ball valves that get confused with each other, full bore and reduced bore ball valves are the most notorious in that regard.\r\n\r\n\r\n\r\n\r\n\r\nWe are going to look at the differences between full bore and reduced bore, their respective functions, how they compare with each other in terms of design and functionality, and the things you have to consider when making a choice between the two. So stick to the end and learn a few helpful tips.\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nGET FULL BORE BALL VALVE PRICE<\/strong><\/a>\r\n\r\n\r\n\r\n\r\nWhat is Full Bore Ball Valve?<\/h2>\r\n\r\n\r\n\r\n\r\nFull bore valves are simply valves that open completely, creating an unobstructed path for gases or liquid being pumped through a tube or pipe. The valve in question is usually smaller than the internal dimensions of the bore of the end connections.\r\n\r\n\r\n\r\n\r\n\r\nThe width of the flow channel in a full bore ball valve is equal all through from the inlet to the outlet, and that diameter size cannot at any point be smaller than the conventional size specifications. The following are the key points that qualify a valve as full bore.\r\n\r\n\r\n\r\n\r\n\r\nAPI 6D and API 608 are some of the full bore sizes that are published by one organization with very slight differences regarding their bore size requirements.\r\n\r\n\r\n\r\n\r\n\r\nFull bore valves range from pressure classes that are limited between 150 to 600, and this includes valve dimensions like API 608 and API 6D. The biggest ones can reach all the way to 2500.\r\n\r\n\r\n\r\n\r\n\r\nThe minimum bore size for a full bore valve should be API 6D.\r\n\r\n\r\n\r\n\r\n\r\nHowever, it is important to note that some valve manufacturers do make slight variations depending on the request of the client, who may want something customized to their needs. For this reason, it is easy to come across some full bore valves that are either bigger or smaller than then given standardized limits.\r\n\r\n\r\n\r\n\r\n\r\nBased on its design, the full bore ball valve is mainly used to transport viscous mediums that are prone to slagging along the pipelines. This is possible due to the low fluid resistance, and this is what makes the movement of heavy materials much easier.\r\n\r\n\r\n\r\n\r\n\r\nConsidering the design of the reducing ball valve, the best application for this type of valve would be in pipelines that convey lighter mediums like gas or materials that are less viscous like water. It has some level of resistance compared to a full bore valve, but this is what makes it perfect for light-medium, as it reduces the pipeline load significantly.\r\n\r\n\r\n\r\n\r\nWhat is Reduced Bore Ball Valve?<\/h2>\r\n\r\n\r\n\r\n\r\nA reduced bore ball valve is a type of ball valve with ball bore diameter less than the pipe diameter. In a reduced bore ball valve, the area of fluid flow is narrower downstream at the outlet. As such, there are frictional losses introduced in the valve resulting in a pressure drop. In reduced bore ball valves, the amount of fluid flow remains constant which makes velocity increase as the flow area decreases. Reduced bore ball valves are commonly used, unlike full bore ball valves. Reduced bore ball valves are used where turbulence and fluid flow rate are not major concerns and where the buildup of particles is not likely to occur. Reduced bore ball valves cost less relative to full bore counterparts. The lower cost of reduced ball valves is because these valves have smaller housing and ball size which affects the final product cost. Reduced bore ball valves occupy a smaller volume which makes them consume small space during installation. Reduced bore ball valves are 30% lighter in weight relative to full bore ball valves. However, reduced bore ball valves are meant for use in fluids that are not very viscous to avoid valve blockage.\r\n\r\n\r\n\r\n\r\nWhat Is The Difference Between Full Bore Ball Valves And Reduced Bore Ball Valves?<\/h2>\r\n\r\n\r\n\r\n\r\nFull bore ball valves mean the bore diameter of the ball is the same as the internal diameter of the pipeline, whatever the inlet or outlet.\r\n\r\n\r\n\r\n\r\n\r\nReduced bore ball valves mean the bore is smaller than the internal diameter of the pipework.\r\n\r\n\r\n\r\n\r\n\r\nReduced bore ball valve has a smaller volume thereby it is easy to install. And it is around 30% lighter than full bore ball valve. What\u2019s more, it has a low cost.\r\n\r\n\r\n\r\n\r\n\r\nBut the full bore ball valve is able to treat highly viscous mediums. However, the reduced bore ball valve is only able to handle some normal mediums like water.\r\n\r\n\r\n\r\n\r\nApplication Media of Full Bore vs Reduced Bore Ball Valve<\/h2>\r\n\r\n\r\n\r\n\r\n \t- 1). The full bore ball valve is generally used for conveying viscous and slagging-prone medium pipelines. Because of its small fluid resistance, it can be said that there is basically no flow resistance, and it is convenient for the regular paraffin scraper and blower to pass through.<\/li>\r\n \t
- 2). The reducing ball valve is suitable for conveying gas or medium with physical properties similar to water, because its weight is about 30% lighter than the full diameter ball valve, and its flow resistance is only about 1 \/ 7 of the same diameter globe valve. It is beneficial to reduce pipeline load and cost.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n
Applicable Process of Full Bore vs Reduced Ball Valve<\/h2>\r\n\r\n\r\n\r\n\r\n \t- 1). For the pipeline requiring regular pigging, a full bore ball valve must be used no matter what medium is transported. When the medium passes through the full bore ball valve, it will not reduce the flow, and the flow resistance is small, which is an ideal product for pipeline control, especially for the strict working condition. In particular, when the main pipelines in oil and gas pipelines need to be buried underground, full bore welded ball valves must be used.<\/li>\r\n \t
- 2). The reducing ball valve is suitable for some working conditions with low requirements and small requirements for convection resistance. When the inner diameter of the valve is more than 80% of the inner diameter of the pipe end, there is little effect on the flow capacity of the pipe. Many valves have a reducing diameter, which is generally controlled within 0.8. On the one hand, reducing diameter reduces the flow capacity of the valve, that is, the Kv value of the valve, increases the pressure drop at both ends of the valve, resulting in energy loss. For the pipeline, it has no great impact or increases the flushing of the pipeline.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n
Comparison of Advantages and Disadvantages<\/h2>\r\n\r\n\r\n\r\n\r\n \t- 1). Installation space: the volume of the reducing ball valve is small, so the requirement of its installation space is smaller. Because its weight is about 30% lighter than the full bore ball valve, it is beneficial to reduce the pipeline load, transportation load, and cost.<\/li>\r\n \t
- 2). Cost: the price of reducing ball valve is one grade lower than that of the full bore ball valve. Considering the cost performance, it generally defaults internationally, and the same ball diameter valve body is adopted for the adjacent pipe diameter. For example, DN32 and Dn40, DN50 and DN63, dn90 and dn110, dn160 and DN200, and DN250 and DN315 use the same sphere.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n
How to Choose?<\/h2>\r\n\r\n\r\n\r\n\r\nUnderstanding the situation of your project like the medium type, pressure, and so on.\r\n\r\n\r\n\r\n\r\n\r\nIf pressure is a factor that you are very concerned about, then you need to know that the reduced bore ball valve will cause pressure drops. And the full bore ball valve won\u2019t.\r\n\r\n\r\n\r\n\r\n\r\nIf your pipeline needs to be cleaned regularly, the full bore ball valve will be your best choice.\r\n\r\n\r\n\r\n\r\n\r\nWe welcome any inquiries from contractors, designers, and distributors.

A v\u00e1lvula esfera de passagem total \u00e9 um canal de fluxo de largura igual, ou seja, o tamanho do canal de fluxo da entrada \u00e0 sa\u00edda \u00e9 o mesmo, e seu tamanho n\u00e3o pode ser menor que o valor especificado na norma, que \u00e9 aproximadamente equivalente ao di\u00e2metro nominal da especifica\u00e7\u00e3o. Por exemplo, o di\u00e2metro do canal de fluxo da v\u00e1lvula esfera de passagem total DN50 deve ser de cerca de 50;<\/li>
- 2). A entrada do caminho de fluxo da v\u00e1lvula esf\u00e9rica redutora \u00e9 mais larga do que o di\u00e2metro do caminho de fluxo, e o di\u00e2metro real do caminho de fluxo \u00e9 cerca de uma especifica\u00e7\u00e3o menor que esta especifica\u00e7\u00e3o. Por exemplo, o caminho de fluxo da v\u00e1lvula esf\u00e9rica redutora DN50 \u00e9 de cerca de 38, que \u00e9 quase o mesmo que o da Dn40. Reduza uma especifica\u00e7\u00e3o dentro de DN250 e duas especifica\u00e7\u00f5es dentro de 250-600, e os 600 acima ser\u00e3o determinados de acordo com a situa\u00e7\u00e3o real.<\/li><\/ul><\/li>
- 2\u3001 M\u00eddia aplic\u00e1vel:
- 1). A v\u00e1lvula de esfera de passagem total \u00e9 geralmente usada para transportar tubula\u00e7\u00f5es m\u00e9dias viscosas e propensas a esc\u00f3ria. Devido \u00e0 sua pequena resist\u00eancia ao fluido, pode-se dizer que basicamente n\u00e3o h\u00e1 resist\u00eancia ao fluxo e \u00e9 conveniente para a passagem do raspador e soprador de parafina normal.<\/li>

A v\u00e1lvula esf\u00e9rica redutora \u00e9 adequada para transportar g\u00e1s ou meio com propriedades f\u00edsicas semelhantes \u00e0s da \u00e1gua, porque seu peso \u00e9 cerca de 30% mais leve que a v\u00e1lvula esf\u00e9rica de di\u00e2metro total e sua resist\u00eancia ao fluxo \u00e9 de apenas cerca de 1\/7 da v\u00e1lvula globo do mesmo di\u00e2metro. \u00c9 ben\u00e9fico reduzir a carga e o custo do gasoduto.<\/li><\/ul><\/li>
- 3. Processo aplic\u00e1vel:
- 1). Para o gasoduto que exige regular pigmenta\u00e7\u00e3o<\/a>, a v\u00e1lvula de esfera de passagem total deve ser usada independentemente do meio transportado. Quando o meio passa pela v\u00e1lvula esf\u00e9rica de passagem total, ele n\u00e3o reduzir\u00e1 o fluxo e a resist\u00eancia ao fluxo \u00e9 pequena, o que \u00e9 um produto ideal para controle de tubula\u00e7\u00f5es, especialmente para condi\u00e7\u00f5es de trabalho rigorosas. Em particular, quando os oleodutos principais em oleodutos e gasodutos precisam ser enterrados no subsolo, devem ser usadas v\u00e1lvulas de esfera soldadas de passagem total.<\/li>
- 2). A v\u00e1lvula de esfera redutora \u00e9 adequada para algumas condi\u00e7\u00f5es de trabalho com baixos requisitos e pequenos requisitos de resist\u00eancia \u00e0 convec\u00e7\u00e3o. Quando o di\u00e2metro interno da v\u00e1lvula \u00e9 superior a 80% do di\u00e2metro interno da extremidade do tubo, h\u00e1 pouco efeito na capacidade de fluxo do tubo. Muitas v\u00e1lvulas t\u00eam di\u00e2metro redutor, que geralmente \u00e9 controlado dentro de 0,8. Por um lado, a redu\u00e7\u00e3o do di\u00e2metro reduz a capacidade de vaz\u00e3o da v\u00e1lvula, ou seja, o valor Kv da v\u00e1lvula, aumenta a queda de press\u00e3o em ambas as extremidades da v\u00e1lvula, resultando em perda de energia. Para o gasoduto, n\u00e3o tem grande impacto, ou aumenta a descarga do gasoduto.<\/li><\/ul><\/li>
- 4. Compara\u00e7\u00e3o de vantagens e desvantagens:
- 1). Espa\u00e7o de instala\u00e7\u00e3o: o volume da v\u00e1lvula esfera redutora \u00e9 pequeno, portanto a necessidade de seu espa\u00e7o de instala\u00e7\u00e3o \u00e9 menor. Como seu peso \u00e9 cerca de 30% mais leve que a v\u00e1lvula de esfera de passagem total, \u00e9 ben\u00e9fico reduzir a carga da tubula\u00e7\u00e3o, a carga de transporte e o custo.<\/li>
- 2). Custo: o pre\u00e7o da v\u00e1lvula esf\u00e9rica redutora \u00e9 um grau inferior ao da v\u00e1lvula esf\u00e9rica de passagem total. Considerando o desempenho de custo, geralmente \u00e9 padronizado internacionalmente, e o corpo da v\u00e1lvula com o mesmo di\u00e2metro de esfera \u00e9 adotado para o di\u00e2metro do tubo adjacente. Por exemplo, DN32 e DN40, DN50 e DN63, DN90 e DN110, DN160 e DN200, DN250 e DN315 usam a mesma esfera.<\/li><\/ul><\/li><\/ul>\n\n\n\n
Como escolher?<\/h2>\n\n\n\n
Compreender a situa\u00e7\u00e3o do seu projeto, como tipo de meio, press\u00e3o e assim por diante.<\/p>\n\n\n\n
Se a press\u00e3o \u00e9 um fator que o preocupa muito, ent\u00e3o voc\u00ea precisa saber que a v\u00e1lvula esfera de di\u00e2metro reduzido causar\u00e1 quedas de press\u00e3o. E a v\u00e1lvula esf\u00e9rica de passagem total n\u00e3o.<\/p>\n\n\n\n
Se a sua tubula\u00e7\u00e3o precisar ser limpa regularmente, a v\u00e1lvula esfera de passagem total ser\u00e1 sua melhor escolha.<\/p>\n\n\n\n

This misunderstanding can lead you to buy the wrong valves for your project. Among the many types of ball valves that get confused with each other, full bore and reduced bore ball valves are the most notorious in that regard.\r\n\r\n\r\n\r\n\r\n\r\nWe are going to look at the differences between full bore and reduced bore, their respective functions, how they compare with each other in terms of design and functionality, and the things you have to consider when making a choice between the two. So stick to the end and learn a few helpful tips.\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\nGET FULL BORE BALL VALVE PRICE<\/strong><\/a>\r\n\r\n\r\n\r\n\r\n
What is Full Bore Ball Valve?<\/h2>\r\n\r\n\r\n\r\n\r\nFull bore valves are simply valves that open completely, creating an unobstructed path for gases or liquid being pumped through a tube or pipe. The valve in question is usually smaller than the internal dimensions of the bore of the end connections.\r\n\r\n\r\n\r\n\r\n\r\nThe width of the flow channel in a full bore ball valve is equal all through from the inlet to the outlet, and that diameter size cannot at any point be smaller than the conventional size specifications. The following are the key points that qualify a valve as full bore.\r\n\r\n\r\n\r\n\r\n\r\nAPI 6D and API 608 are some of the full bore sizes that are published by one organization with very slight differences regarding their bore size requirements.\r\n\r\n\r\n\r\n\r\n\r\nFull bore valves range from pressure classes that are limited between 150 to 600, and this includes valve dimensions like API 608 and API 6D. The biggest ones can reach all the way to 2500.\r\n\r\n\r\n\r\n\r\n\r\nThe minimum bore size for a full bore valve should be API 6D.\r\n\r\n\r\n\r\n\r\n\r\nHowever, it is important to note that some valve manufacturers do make slight variations depending on the request of the client, who may want something customized to their needs. For this reason, it is easy to come across some full bore valves that are either bigger or smaller than then given standardized limits.\r\n\r\n\r\n\r\n\r\n\r\nBased on its design, the full bore ball valve is mainly used to transport viscous mediums that are prone to slagging along the pipelines. This is possible due to the low fluid resistance, and this is what makes the movement of heavy materials much easier.\r\n\r\n\r\n\r\n\r\n\r\nConsidering the design of the reducing ball valve, the best application for this type of valve would be in pipelines that convey lighter mediums like gas or materials that are less viscous like water. It has some level of resistance compared to a full bore valve, but this is what makes it perfect for light-medium, as it reduces the pipeline load significantly.\r\n\r\n\r\n\r\n\r\n
What is Reduced Bore Ball Valve?<\/h2>\r\n\r\n\r\n\r\n\r\nA reduced bore ball valve is a type of ball valve with ball bore diameter less than the pipe diameter. In a reduced bore ball valve, the area of fluid flow is narrower downstream at the outlet. As such, there are frictional losses introduced in the valve resulting in a pressure drop. In reduced bore ball valves, the amount of fluid flow remains constant which makes velocity increase as the flow area decreases. Reduced bore ball valves are commonly used, unlike full bore ball valves. Reduced bore ball valves are used where turbulence and fluid flow rate are not major concerns and where the buildup of particles is not likely to occur. Reduced bore ball valves cost less relative to full bore counterparts. The lower cost of reduced ball valves is because these valves have smaller housing and ball size which affects the final product cost. Reduced bore ball valves occupy a smaller volume which makes them consume small space during installation. Reduced bore ball valves are 30% lighter in weight relative to full bore ball valves. However, reduced bore ball valves are meant for use in fluids that are not very viscous to avoid valve blockage.\r\n\r\n\r\n\r\n\r\n
What Is The Difference Between Full Bore Ball Valves And Reduced Bore Ball Valves?<\/h2>\r\n\r\n\r\n\r\n\r\nFull bore ball valves mean the bore diameter of the ball is the same as the internal diameter of the pipeline, whatever the inlet or outlet.\r\n\r\n\r\n\r\n\r\n\r\nReduced bore ball valves mean the bore is smaller than the internal diameter of the pipework.\r\n\r\n\r\n\r\n\r\n\r\nReduced bore ball valve has a smaller volume thereby it is easy to install. And it is around 30% lighter than full bore ball valve. What\u2019s more, it has a low cost.\r\n\r\n\r\n\r\n\r\n\r\nBut the full bore ball valve is able to treat highly viscous mediums. However, the reduced bore ball valve is only able to handle some normal mediums like water.\r\n\r\n\r\n\r\n\r\n
Application Media of Full Bore vs Reduced Bore Ball Valve<\/h2>\r\n\r\n\r\n\r\n
- \r\n \t
- 1). The full bore ball valve is generally used for conveying viscous and slagging-prone medium pipelines. Because of its small fluid resistance, it can be said that there is basically no flow resistance, and it is convenient for the regular paraffin scraper and blower to pass through.<\/li>\r\n \t
- 2). The reducing ball valve is suitable for conveying gas or medium with physical properties similar to water, because its weight is about 30% lighter than the full diameter ball valve, and its flow resistance is only about 1 \/ 7 of the same diameter globe valve. It is beneficial to reduce pipeline load and cost.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n
Applicable Process of Full Bore vs Reduced Ball Valve<\/h2>\r\n\r\n\r\n\r\n
- \r\n \t
- 1). For the pipeline requiring regular pigging, a full bore ball valve must be used no matter what medium is transported. When the medium passes through the full bore ball valve, it will not reduce the flow, and the flow resistance is small, which is an ideal product for pipeline control, especially for the strict working condition. In particular, when the main pipelines in oil and gas pipelines need to be buried underground, full bore welded ball valves must be used.<\/li>\r\n \t
- 2). The reducing ball valve is suitable for some working conditions with low requirements and small requirements for convection resistance. When the inner diameter of the valve is more than 80% of the inner diameter of the pipe end, there is little effect on the flow capacity of the pipe. Many valves have a reducing diameter, which is generally controlled within 0.8. On the one hand, reducing diameter reduces the flow capacity of the valve, that is, the Kv value of the valve, increases the pressure drop at both ends of the valve, resulting in energy loss. For the pipeline, it has no great impact or increases the flushing of the pipeline.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n
Comparison of Advantages and Disadvantages<\/h2>\r\n\r\n\r\n\r\n
- \r\n \t
- 1). Installation space: the volume of the reducing ball valve is small, so the requirement of its installation space is smaller. Because its weight is about 30% lighter than the full bore ball valve, it is beneficial to reduce the pipeline load, transportation load, and cost.<\/li>\r\n \t
- 2). Cost: the price of reducing ball valve is one grade lower than that of the full bore ball valve. Considering the cost performance, it generally defaults internationally, and the same ball diameter valve body is adopted for the adjacent pipe diameter. For example, DN32 and Dn40, DN50 and DN63, dn90 and dn110, dn160 and DN200, and DN250 and DN315 use the same sphere.<\/li>\r\n<\/ul>\r\n\r\n\r\n\r\n
How to Choose?<\/h2>\r\n\r\n\r\n\r\n\r\nUnderstanding the situation of your project like the medium type, pressure, and so on.\r\n\r\n\r\n\r\n\r\n\r\nIf pressure is a factor that you are very concerned about, then you need to know that the reduced bore ball valve will cause pressure drops. And the full bore ball valve won\u2019t.\r\n\r\n\r\n\r\n\r\n\r\nIf your pipeline needs to be cleaned regularly, the full bore ball valve will be your best choice.\r\n\r\n\r\n\r\n\r\n\r\nWe welcome any inquiries from contractors, designers, and distributors.
