Válvula EW
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.
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 Process Management.
