Three-piece stainless steel ball valves are versatile and robust components widely used in industrial applications for fluid control.  This article will discuss everything you need to know about 3-piece stainless steel ball valves. Types of Three Piece Ball Valves 1. Full Port vs. Standard Port Full Port Ball Valve The valve’s inside opening, or “port,” is as wide as the pipeline, allowing for maximum flow. It is good for applications where high flow rates are important. Standard Port Ball Valve The inside opening is smaller than the pipeline, which can restrict the flow slightly. Suitable for applications where a slightly reduced flow is acceptable. 2. Manual vs. Automated Manual 3-Piece Ball Valve Operated by hand using a lever or a handwheel. Simple and cost-effective for applications where manual control is sufficient. Automated 3-Piece Ball Valve Equipped with an actuator for automatic operation. Ideal for processes that require remote or automated control. Materials Used in 3 Piece Ball Valves 1.

Cuando se trata de válvula industrial selección, las válvulas de bola con conexiones finales bridadas ofrecen una solución robusta con algunos beneficios distintivos. Mientras que los extremos roscados y para soldar tienen su lugar, las válvulas de bola con bridas destacan para muchos servicios exigentes y aplicaciones críticas. El diseño robusto del cuerpo con bridas, el fácil mantenimiento y la versatilidad en materiales y configuraciones hacen de estas válvulas una opción confiable en innumerables instalaciones. Si está considerando instalar una nueva válvula de bola, vale la pena explorar si una opción con brida es la opción óptima. Válvula de bola con brida - Beneficios claveSi se pregunta: “¿Son mejores las válvulas de bola con brida?” ”, estas son algunas de las ventajas clave que las válvulas de bola con bridas pueden ofrecer sobre conexiones finales alternativas:1.Capacidad para soportar presiones más altasCon su robusta construcción de cuerpo de dos piezas, las válvulas de bola con bridas pueden soportar índices de presión significativamente más altos en comparación con las unidades roscadas. Las bridas crean un diseño a prueba de explosiones al contener fuerzas dentro del conjunto de cuerpo rígido.Algunas válvulas bridadas alcanzan presiones nominales superiores a 5800 psi para aplicaciones duras y de servicio severo. Los límites de presión de alta integridad son fundamentales para aplicaciones como producción de petróleo/gas, sistemas de vapor, plantas de procesamiento químico y más. Las conexiones embridadas proporcionan los márgenes de seguridad requeridos.2. Diseño de paso total para restricción mínima de flujoLa válvula de bola con extremo de brida generalmente presenta un diseño de paso total donde la cavidad interna de la bola coincide con el diámetro interno de la tubería. Esta área abierta permite una ruta de flujo sin restricciones cuando está abierta con una caída de presión o resistencia al flujo mínimas.Otros tipos de conexiones finales pueden utilizar puertos reducidos, formas venturi o tapones que pueden impedir el flujo y aumentar la turbulencia. La configuración bridada de paso total es ideal para lodos, servicios públicos de gran volumen y aplicaciones donde es necesario minimizar la pérdida de carga.3.Mantenimiento simplificado y eliminación en líneaQuizás la mayor ventaja de las bridas es la fácil extracción de la válvula de la tubería sin necesidad de realizar tomas en caliente ni roturas de línea. Las conexiones de los extremos atornillados permiten un desmontaje rápido para mantenimiento o reemplazo simplemente desatornillando las bridas.Esto elimina la necesidad de cortar, roscar, volver a soldar tuberías y otros procedimientos invasivos y costosos. La mantenibilidad en línea es un beneficio importante para los servicios críticos, ya que reduce el costoso tiempo de inactividad. El fácil acceso también simplifica la inspección interna, el reempaque, el reemplazo de juntas y los cambios de piezas.4.Capacidad para manejar temperaturas y medios extremosLa construcción con bridas permite una amplia selección de materiales y accesorios para el cuerpo de la válvula para manejar medios corrosivos y temperaturas extremas. Las opciones incluyen acero al carbono, acero inoxidable, aleaciones con alto contenido de níquel, titanio y combinaciones especiales de metal/revestimiento.Estas robustas opciones de metalurgia brindan una excelente resistencia química y permiten que las válvulas de bola con bridas funcionen de manera confiable en las aplicaciones de refinería, productos químicos y lodos más duras. El diseño bridado evita posibles debilidades de las conexiones roscadas en estos servicios.ConclusiónSi bien hay aplicaciones en las que las conexiones soldadas roscadas o encastradas son adecuadas, las válvulas de bola con bridas brindan ventajas innegables para muchos usos industriales. Su contención de presión, características de flujo, mantenibilidad y flexibilidad de materiales los convierten en una excelente opción para servicios críticos.
