Válvula EW
Julio de 2017
Lista de piezas
Debido a las numerosas combinaciones disponibles de
piezas de válvulas, la selección de algunas piezas es difícil;
cuando se hace un pedido de piezas de válvulas para las
cuales no se encuentra el número de pieza en la lista, se
debe proporcionar el número de serie de la válvula con el
pedido, permitiendo así que se haga una adecuada selección
de las piezas de reemplazo en la fábrica.
Nota
Sólo se indican los números de referencia de las piezas de repuesto
recomendadas. Para obtener los números de referencia de piezas de
repuesto que no estén incluidas, consultar a la oficina de ventas de
Emerson Automation Solutions.
