Abstract

Un ensamble de válvula de derivación para su uso en generadores de turbina incluye un cuerpo de válvula que define un orificio central y una pluralidad de pasajes. Cada pasaje tiene un área más pequeña en una parte de entrada y un área más grande en una porción de salida para definir una pasaje abocinado. Una pluralidad de válvulas de derivación está dispuesto dentro de la pluralidad de pasajes dentro del cuerpo de la válvula. Cada válvula de derivación incluye una porción de base y una parte de nariz, con cada parte de nariz que define un área de superficie contorneada predefinida. Al menos una porción de la superficie contorneada incluye un recubrimiento de desgaste dispuesto sobre el mismo. Opcionalmente, el recubrimiento de desgaste incluye un nano-recubrimiento de PEMS (bombardeo iónico de magnetrón de plasma mejorado).
